摘　　要：Pr^3＋/Yb^3＋ co-doped CaNb206 thin films are deposited on Si（100） substrates by pulsed laser deposition and anneMed 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 Pr^3＋/Yb^3＋ co-doped CaNb206 films increases with the increasing annealing temperature.Pr^3＋/Yb^3＋ co-doped CaNb206 thin films are deposited on Si（100） substrates by pulsed laser deposition and anneMed at different temperatures in air atmosphere.
