| Abstract Scope |
Y(0.90−x),Li(x))BO(3−δ):Tb0.10film was fabricated via co-precipitation of lithium and terbium within yttrium borate. The doping concentration of lithium (1%, 3% and 5%) studied in detail. The structure, morphology and optical properties of the YBO3 matrix under the co-doping of Tb and Li were investigated. The XRD diffraction peaks were confirmed as the typical characteristic of hexagonal YBO3. With the increase of the doping concentration of Li3+, the intensity of the diffraction peak in the graph increases, indicating that the addition of Li3+ sufficiently improved the crystallinity of films. The surface of films was found to comprise with irregular particles of an average size 200-400 nm. The luminescence intensity of the film was found to increase within 1%-3% and decrease as the doping concentration of Li at 3%-5%. |
