Silicon Nitride Ceramics:

The development of silicon nitride OLED materials is the basis for the vigorous development of the OLED industry. The earliest OLED light-emitting materials are fluorescent materials, but the upper limit of the theoretical quantum efficiency of fluorescent materials can only reach 25% due to spin inhibition. In 1998, Ma and Forrest and Thompson successively reported the application of phosphorescent materials in OLED materials, which paved the way for breaking the law of spin statistics and utilizing 100% of the energy of all excitons. However, phosphorescent materials also have certain problems. Due to the inclusion of precious metals, the price is high and the stability of blue light materials has been stagnant for a long time.
In 2009, Professor Adachi from Kyushu University in Japan introduced thermally activated delayed fluorescence (TADF) materials into OLEDs for the first time. Such materials have extremely low singlet triplet energy gaps and can achieve 100% intra-theoretical quantum efficiency through inverse intersystem crossing (RISC) of triplet excitons. With the improvement of material system and device structure, OLED has emerged in the display field. On the other hand, WOLED, which incorporates "Silicon Nitride Ceramic Plate", has a series of advantages such as high luminous efficiency, adjustable spectrum, less blue light components and surface light source. As a high-efficiency light source with low color temperature and no blue pollution, it is expected to become a new trend of healthy lighting in the future.
