Abstract
In this paper, nanoscale Tb3+ doped CaMO4 (M: W, Mo) were prepared by a facile and mild solid-state double exchange method. The structures, morphologies, temperature stability and fluorescence properties of the obtained phosphors were characterized by XRD, SEM, Raman, FT-IR and PL, respectively. Based on the phosphors, the luminescent films and LED optical devices were fabricated. In addition, the detections of Cr2O72− and 4-nitrophenol (4-NP) were successfully achieved. The results showed that the detecting platform have good selectivity and sensitivity. Therefore, Tb3+ doped CaMO4 (M: W, Mo) phosphors could be an eminent candidate for versatile application prospect.
