Planar waveguides based on nanocrystalline and Er3+ doped SnO2
(Trans Tech Publications Ltd, 2002-01-01)
Luminescent SnO2: x%mol Er3+ (x=0.1-2.0) thin films have been spin coated on borosilicate and silica substrates from water colloidal suspensions that could be prepared containing up to 40% in weight SnO2 nanocrystalline ...
Rare Earth Doped SnO(2) Nanoscaled Powders and Coatings: Enhanced Photoluminescence in Water and Waveguiding Properties
(Amer Scientific Publishers, 2011-03-01)
Luminescent Eu(3+) and Er(3+) doped SnO(2) powders have been prepared by Sn(4+) hydrolysis followed by a controlled growth reaction using a particle's surface modifier in order to avoid particles aggregation. The powders ...
