| 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:xTm<3+>, yHo<3+>, wherein Tm<3+> and Ho<3+> are doping ions, a is 0.5-0.7, b is 0.15-0.3, c is 0.06-0.13, x is 0.01-0.08, y is 0.01-0.06, 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 spray pyrolysis 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. |
