8 new technologies for solid state luminescent materials that could change the future of lighting

Recently, some industry experts have pointed out that the solid-state lighting of new technology and new materials can not be ignored, solid state lighting of new materials and new technologies, especially mentioned a number of years will be a number of nanometer material industry, will change the future of lighting the world, it will bring great challenges to the existing semiconductor lighting, and lighting will change the future of the world. This brings great challenges to existing semiconductor lighting. However, the ability to enter the field of lighting, the only criterion is to evaluate the overall product ratio, that is, energy efficiency indicators, color quality, reliability and price ratio.

In fact, the development of new solid materials, especially graphene, phosphinidene, two-dimensional semiconductor material MX2, perovskite, besides having luminescent properties, can be used for the preparation of high performance electronic devices, sensors, detectors, memory and optoelectronic devices, once the application technology mature and industrialization, it is technological innovation subversive, also will have a profound impact on the electronic information industry. Here we come one by one inventory, together with understanding.

Graphene

Graphene as a new material, has become a hot pursuit of capital. Data show that China's existing graphene Industry 1000 enterprises, but many local governments are keen to develop graphene industry policy for graphene be busy at putting up installations, from the park. Some companies are frequently to universities and research institutions to extend the olive branch of cooperation in graphene research and development projects. Mask, a famous American entrepreneur, has predicted that the future life mileage of the electric vehicle with built-in graphene polymer material can reach 800 km, which has reached the level of the traditional automobile. This prediction provides a huge imagination for the development of graphene industry.

During the 12th Five-Year China graphene industry in-depth market research and investment strategy planning analysis report shows that China has applied for more than 2200 graphene patented technology, accounting for the world's total number of graphene patents 1/3. According to the state property administration, Wind database data, in 2015 the number of patent applications in China reached 7925, ranking first in the world. In fact, in the "12th Five-Year" period, China's local governments have aimed at the graphene in this new material, and have set up a series of graphene industry base, including Ningbo Industrial Park, Changzhou Jiangnan graphene graphene Research Institute, Wuxi graphene industry demonstration zone, Qingdao international graphene Innovation Center Chongqing Industrial Park, Sichuan Province graphene graphene industrial park. In addition, Beijing, Anhui, Heilongjiang, Hunan and other provinces have begun to plan the development of graphene industry plan.

Preliminary statistics, investment in research and development of graphene materials and applications at present developed countries including the United States, European Union, Japan and other more than and 80 countries and regions, and the United States, Britain, South Korea, Japan and the European Union will be upgraded to the strategic height of graphene research, expect it to bring a huge market value. According to incomplete statistics, the world's nearly 300 companies involved in the research and development of graphene, including IBM, Intel, SanDisk, Dow Chemical, general motors, DuPont, Xerox, Samsung, Lockhead Martin, Boeing and other tech giants. However, despite the fact that the graphene industry is a large patent country, but the conversion rate is not high. The important thing is the scientific and technological innovation, make full use of "enterprise + research institutions + market" model.

Organic light emitting diode (OLED)

In recent years, OLED lighting technology are more and more applications, and even became the academic and industrial circles, according to most of the hot topics of research, has now removed the veil of mystery, into people's daily life gradually.

OLED lighting, according to the latest survey data provided by the market group showed that this vehicle OLED lighting panel market share has reached 72 million yuan, compared with the same period last year increased by nearly five percentage points, in this regard, experts predict that by 2017, the market is expected to exceed 100 million yuan.

As a high-end lighting source, OLED lighting in order to achieve the characteristics of the plane light emitting a very natural light, ultra-thin, flexible, arbitrary shape of the advantages of light source, is now synonymous with high-quality environmentally friendly light source. As one of the hottest technologies in the lighting industry, OLED lighting since the date of its own will be sought after by the industry and outside.

OLED has a very good photochromic performance, will soon enter the field of lighting. Seoul Research Institute predicts that by 2020, OLED lighting output value of $4 billion 700 million, Taiwan optoelectronics predicted LED in 2020 and OLED lighting output ratio of 3:1, while another expert forecast of 1/4.

Laser illumination

Laser lighting has two different technical routes, that is, white light emitting laser and future laser lighting. The University of Arizona study of a nano thickness by zinc and cadmium, sulfur and selenium in ZnCdSSe, ensure that the crystal nanosheets coexist, is divided into three parts, in the light pulse under the excitation of R laser, G, B three color, mixed into white light, can be used for lighting, also can be used in optical communication, optical response rate than the ordinary LED 10 ~ 100 times faster.

Nobel laureate Nakamura Shuji has repeatedly said that laser lighting is the future of lighting point of view. June 25, 2016, Nakamura Shuji attended the 2016 China Chengdu global innovation and entrepreneurship fair when interviewed by the media had boldly predicted: the next ten years, laser lighting will replace LED lighting.

Nakamura Shuji believes that in the field of his research, 10 years later, laser lighting is likely to replace the current LED lighting. According to the village
