Synthetic methods and application of upconversion luminescence materials

The paper presents the research for the rare-earth luminescence materials in recent years,and introduces mainly the characteristics,the compounding method,the application,the production and the prospect of rare-earth luminescence materials in China.

The red long afterglow phosphorescent material Y_(2)O_(3)∶Eu~(3+),Ca~(2+),Ti~(4+) is fabricated from the method of combustion synthesis,by using urea as the reductant and the nitrates of Y~(3+) as the oxidant.

A red long afterglow phosphorescent material Y_2O_3∶Eu~(3+),Ca~(2+),Ti~(4+) was fabricated by the method of combustion synthesis,using urea as the reductant and yttrium nitrate as the oxidant.

The long afterglow phosphor CaAl_2O_4∶Eu~(2+),Nd~(3+) was coated by SiO_2 with sol-gel method to resist its degradation in moisture surroundings.

The luminescence materials of xSrO·yAl2O3∶Eu2+ were synthesized by microwave radiation method.

1 luminescence materials were prepared by sol-gel method and calcined at different temperatures from 250 to 1000℃.

The cur- rent status and main problems of this synthesis method of rare earth luminescence materials are introduced in detail.

With the wide application of self-lighting materials in security field, the demands for self-lighting signs has even in- creased.
