The intensity of erbium up-conversion luminescence could be limited by a saturation effect due to increased pump power. We studied the luminescence saturation of the 550 nm emission on erbium-doped, SiO2–TiO2 sol–gel powders under pulsed excitati

Spectroscopic properties of erbium ions in SiO 2 -TiO 2 -Er 3+ powders are studied and the nature of the emissions discussed. A strong green luminescence and less intense red and blue emissions were observed in the samples when exciting at 490 nm, 53

The TiO2 content was changed from low to high concentration (5–70% molar) in binary erbium doped SiO2–TiO2 powder samples produced by the sol–gel method. Three pumping wavelengths 532, 979 and 1532 nm, were used to study the blue up-conversion
