Abstract :
The upconversion processes in erbium doped sol-gel SiO2 are studied. The photoluminescence was measured for selected sol-gel samples and compared with the results of the rate equation model. The results show that the presence of cooperative upconversion processes in erbium doped materials can be easily verified experimentally by measuring the photoluminescence spectrum.
