Effect of Li Content, Deposition Time and Solution Concentration on Morphology and Photoluminescence Properties of Y2O3: 5%Eu3+, x%Li+ Thin Film.

Y 2 O 3 : 5%Eu 3+ , x %Li + phosphor thin film was fabricated via an electro-deposited method. The dependence of the morphology and luminescent properties for Y 2 O 3 : 5%Eu 3+ , x %Li + thin film on Li content, deposition time and solution concentration were studied. The results indicate that the morphology and the emission intensity strongly depend on the Li content, deposition time, and solution concentration. It is found that the Li addition is beneficial to the formation of flower morphology and then enhances the photoluminescence intensity. The optimal Li content is 15% for Y 2 O 3 : 5%Eu 3+ , x %Li + .
