COLOR-ADJUSTABLE LUMINESCENT POWDER AND PREPARATION METHOD THEREOF |
摘要 |
A color-adjustable luminescent powder is provided, the chemical general formula of which is (YaGdbEuc)2O3·xZn(1-m)AlmO, wherein 0 = a = 0.99, 0 = b = 0.99, 0.01 = c = 0.08, provided that a+b+c=1 and a and b are not 0 simultaneously; x is the molar ratio between Zn(1-m)AlmO and (YaGdbEuc)2O3, 0.01 = x = 0.20,and 0.001 = m = 0.05. A preparation method of the above luminescent powder is also provided, which comprises the following steps: adding an aqueous alcohol solution containing a complexing agent, and a surfactant to a mixed solution containing needed components to obtain a precursor solution, then aging the precursor solution, undergoing calcination treatment and cooling down to obtain the said luminescent powder. |
