Monolithic silica xerogels doped with different concentrations of Er, Yb and Al were prepared by sol-gel route. We studied the luminescence properties of the emission band of Erbium ions around 1.5 micron as a function of the Al/Er/Yb ratio and we paid particular attention to the alumina effects.

Abstract
Monolithic silica xerogels doped with different concentrations of Er, Yb and Al were prepared by sol-gel route. We studied the luminescence properties of the emission band of Erbium ions around 1.5 micron as a function of the Al/Er/Yb ratio and we paid particular attention to the alumina effects.File in questo prodotto:
