Abstract Scope |
The YBO3 films with Tb3+ doping were prepared by sol-gel and impregnation-lifting method. The surface of Y1-xTbxBO3 film is uniformly arranged in nanocrystals and consists of irregular particles with a particle size of 100-200 nm. The luminescence intensity of Y1-xTbxBO3 films was found to increases in the first stage and then decrease with the doping percentage of Tb3+. The amount of dosage of 10% Tb3+ was confirmed to be more favorable in achieving a higher degree of crystallinity as well as large specific surface area. The film has a mean square roughness of 19.8 nm based on the AFM analysis. The octahedral coordinated Y3+ was indicated to be substituted by Tb3+ judged from radius calculation. The strongest peak in the UV excitation spectrum of Y1-xTbxBO3 film was found at 539 nm is at 358 nm. Two emission peaks in Y1-xTbxBO3 film were located at 485 nm and 539 nm |
