dc.description.abstractRecentlya considerable interest has been shown on the studies of photo-luminescence (PL) of lanthanides doped oxide ceramics. The group of rare-earth ions exhibits unique PL bands at particulate wavelengths that are highly independent from the host matrix. However, width and intensity of PL bands frequently change with the host material. ions are one of the best candidates to study luminescence properties compared to other lanthanide elements (Nogami, 2002). In this study, Eu ions were bonded to ZnO ceramic via organic molecules. Further enhancement of luminescence bands was observed by coupling with selected oligomers to Eu ions. A hetero-junction was prepared by depositing copper-thiocyanate on surface modified zinc oxide ceramic. Red light emission was observed from the surface bounded Eu ZnO:Eu |CuSCN hetro-junction under reverse bias. ions of Methodology ZnO was deposited on Fluorine doped tin oxide (FTO) coated glass substrates as previously discussed (Sirimanne et al, 2011). ZnO thin films were kept immersed in 2,2'-bipyridyl 4,4'- dicarboxylic acid (abbreviated as dcbpy, 200 μM in ethanol), EuCl3 (1 mM in ethanol) and 2- thenoyltrifluoroacetone (abbreviated as TTA, 200 μM in ethanol) for one hour in each solution in order.en_US
