چکیده
Co-doping Ce3+ ions and size-tunable SnO2 nanocrystals into Tb3+ embedded silica thin films produces a ninefold enhancement of related emission. Firstly, by optimizing the doping ratio Sn4+ annealing temperature, size nanoparticles was well tailored for achieving greatly enhanced photoluminescence emission from ions. In order to further increase ions, proper concentration were also added material. The co-doping situation researched in this work. Tb3 + reaches top when recorded 15% 2%. On other side, companied with concentration, growth CeO2 proved seriously attenuated intensity Therefore, reducing gas phenomenon process could be very important. Finally, analyzing temperature co-doped sample, we conclude that high such as 1000℃ can enhance well. These results indicated an appropriate proportion suitable effectively sensitize luminescence

The green (537 and 558 nm) and near infrared (1.54 mm) photoluminescence (PL) spectra of Er-doped GaN thin films have been investigated as a function of temperature, excitation wavelength, and pump intensity. Thermal quenching measurements showed that the 31 4 2 4 integrated green Er PL intensity ( S / H → I ) remained nearly constant up to 150 K, but decreased at higher temperatures 3 / 2 11 /...
