采用脉冲激光沉积方法在 Si(100) 衬底上沉积 Pr3+/Yb3+ 共掺杂 CaNb2O6 薄膜，并在空气气氛中不同温度下进行退火。 X 射线衍射、拉曼光谱、原子力显微镜、X 射线光电子能谱和光致发光光谱用于表征样品。结果表明，退火温度对薄膜的晶粒尺寸、结构、形貌和上转换发光性能有很大影响。 Pr3+/Yb3+共掺杂CaNb2O6薄膜的晶粒尺寸和上转换发光随着退火温度的升高而增大。
Pr3+/Yb3+ co-doped CaNb2O6 thin films are deposited on Si(100) substrates by pulsed laser deposition and annealed at different temperatures in air atmosphere. X-ray diffraction, Raman spectroscopy, atomic force microscopy, X-ray photoelectron spectroscopy, and photoluminescence spectra are used to characterize the samples. The results show that the annealing temperature has a strong effect on the film's grain size, structure, morphology, and the up-conversion luminescence properties. The grain size and up-conversion luminescence of Pr3+/Yb3+ co-doped CaNb2O6 films increases with the increasing annealing temperature.
