The Kero State Organic Optoelectronics Research Center of Kyushu University in Japan recently developed a new type of strong fluorescent material for organic light-emitting diodes (O LEDs ) that uses only fluorescent materials as raw materials and has a luminous efficiency of 90% or more. The effect is equivalent to the luminous efficiency using phosphorus as a raw material, but the cost is greatly reduced. According to reports, according to the principle of light emission , the raw materials of the existing O led luminescent materials mainly include fluorescent materials and phosphorescent materials. The luminous efficiency of the fluorescent material is up to 25%, and the phosphorescent material is 100%. The newly developed strong fluorescent material is capable of generating a thermally active delayed fluorescence phenomenon, and its luminous efficiency can be as high as that of the phosphorescent material when it is excited by light. Another highlight of the material is the wide selection of luminescent colors that can be used to make Oled panels of luminescent colors such as blue, green, yellow-green, yellow and orange.
