Temperature Properties of Fluorescence Spectra in Tm3+-Doped LaOF and SiO2 Nanosystems
Fluorescence spectra of Tm3+-doped LaOF and SiO2 nanosystems at different temperatures are investigated, which show that line width, intensity of fluorescence and spectra position all change with the increase of temperature in the range of 20~300 K. Dependency on temperature of fluorescence spectra is influenced directly by local environment. Fluorescence lifetime of active ions in SiO2 uncrystal phase is less affected, while it is largely affected in LaOF crystal phase ambient. The rule reliance upon temperature of 3H4 lifetime is studied under pulsed laser excitation.
