摘 要: | 本实验改进了传统的制备氧化钇铕荧光粉的方法,采用不同于"化合法"和"混合法"的实验室内常用的"干湿结合法",将Ba2+,Y3+,Eu3+用不同的溶液分步沉淀,然后再灼烧沉淀,制备出掺有BaSO4的红色荧光粉(Y,Eu)2O3.并对所得样品的发射光谱进行了测试.结果表明,在本实验改进条件下制备的荧光粉,发光强度有所提高,并且降低了该荧光粉的成本.

Development of Phosphor on the Plant- growth Light |
| |
Abstract: | The traditional preparation of (Y,Eu)2O3 was modified .Combining the compounding and the mixed methods, an usual method in lab has been developed . By precipitating Ba2+,Yand Eu3+ ions in stages ,and then calcinating the precipitate ,BaSO4mixed (Y,Eu)2O3 red-emitting phosphor was synthesized. The sample emmision spectra was measured. It was found that in this experiment,the sample luminescence intensity had been improved and its cost had been lowered. |
