Fig. 6From: Study of energy transfer mechanism from ZnO nanocrystals to Eu3+ ionsThe intensity difference from ZnO-nc emission centres. The intensity difference between ZnO-nc:SiO2 and Eu3+ 0.12:(ZnO-nc:SiO2) samples annealed at 450 °C which is due to the incorporation of Eu3+ ionsBack to article page
