Abstract
The temperature dependence of upconversion luminescence in tri-doped single crystal was studied at different temperatures from 289 to 773 K under 980 nm excitation. The tri-doped single crystal offers temperature-dependent color tuning properties, and the white-light emission can be obtained by simply tuning the temperature. In addition, the competition between nonradiative transition and thermal population plays an important role in the upconversion process with temperature increase. This research has implications in the extension of research for optical temperature sensors and multicolor variable temperature display materials.
