New quantum dot manufacturing technology will bring a new era of LED lighting?

Abstract: according to the American Institute of electrical and electronic engineers "spectrum" magazine website reported that researchers at the Oregon State University recently demonstrated a new quantum dot manufacturing technology, can not only ensure made quantum dot size and shape can be more accurate consistent from beginning to end, the color control, may mean that the new era of the advent of LED lighting.

Quantum dots have had a wide range of commercial impact on LED technology, and now, the focus of the research is to improve the manufacturing process and increase profits. According to the American Institute of electrical and electronic engineers "spectrum" magazine website reported that researchers at the Oregon State University recently demonstrated a new quantum dot manufacturing technology, can not only ensure made quantum dot size and shape can be more precise consistent from beginning to end, the color control, may mean that the new era of the advent of LED lighting.

In a study published in the Journal of nanoparticle research, the team used a chemical reactor called a "continuous flow". The chemical is continuously put into the reactor and produces continuous LED illumination. This continuous flow device makes the process of making LED lighting cheaper, faster, and highly scalable. At the same time, they use microwave to heat the reagent, which solves the problem of how to control the temperature accurately in the chemical reaction. The microwave device is similar to the operating principle of the microwave oven you use at home.

The researchers believe that this approach will bring great changes in the field of LED lighting. Since this method can be used to make quantum dots with the same size and shape, the flexibility of the device ensures that the manufacturer can produce quantum dots with various purposes. Smaller quantum dots can release green light, and larger quantum dots can release orange to red light.

"We may eventually be able to produce low-cost, energy-efficient LED lighting, and can achieve the desired effect of white light," said Greg Hermann, associate professor of chemical engineering at the university. The research team believes that compared with other quantum dot manufacturing technology, their precise manufacturing methods can bring better color control.

At the same time, this technology uses non toxic materials, and greatly reduce the waste of materials, which will reduce the cost of production, environmental protection. Herman explained that, compared with the commonly used cadmium in the LED lighting system, the use of copper indium selenide selenium material is more environmentally friendly.

The researchers said that the quantum dots produced by this method can be used in optics, electronics, biomedical and other fields to provide another cheap option.
