Rare earth centers properties and electron trapping in SnO2 thin films produced by sol-gel route
(Journal of Non-Crystalline Solids, 2008-11-01) [Artigo]
Some very relevant optical. electrical, and structural properties of SnO2 doped with rare-earth ions Er3+ and Eu3+ are presented. Films are produced by the sol-gel-clip coating process, and may be described as a combination ...
Raman and photoluminescence of Er3+-doped SnO2 obtained via the sol-gel technique from solutions with distinct pH
(Optical Materials, 2010-11-01) [Artigo]
Raman and infrared photoluminescence measurements are carried out for Er3+-doped SnO2 pellets (hard-pressed powders) obtained by the sol-gel technique from colloidal suspensions with distinct pH. Raman data indicate that ...
