Rare earth centers properties and electron trapping in SnO2 thin films produced by sol-gel route
(Elsevier B.V., 2008-11-01)
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 ...
