| titleOfInvention | Zirconium-beryllium alkali fluoride upconversion luminescent fluorescent powder, preparation method thereof and organic light emitting diode (OLED) |
| abstract | The invention relates to zirconium-beryllium alkali fluoride upconversion luminescent fluorescent powder, a preparation method thereof and an organic light emitting diode (OLED). The chemical formula of the fluorescent powder is aZrF4-bBeF2-cRF:xDy<3+>, wherein Dy<3+> is a doping ion, a is 0.5-0.7, b is 0.15-0.27, c is 0.11-0.15, x is 0.01-0.08, and R is any one of Li, Na, K, Rb and Cs. According to the zirconium-beryllium alkali fluoride upconversion luminescent fluorescent powder prepared by adopting a chemical coprecipitation method, disclosed by the invention, blue-light short-wavelength luminescence can be excited through infrared-to-red green light long-wavelength radiation, so that the defect of the current luminescent materials that blue-light materials are insufficient is made up; according to the preparation method, the purity of the fluorescent powder is improved, so that the structural stability and luminescent intensity of light emitting devices are further improved; due to a relatively low synthesis temperature, the complexity of a preparation process is lowered, and the preparation cost of the preparation process is reduced. |
