Abstract

Pure tetragonal-phased Ca0.9MoO4:0.1Eu3+ (CaMoO4:Eu3+) microcrystals with varying particle sizes were prepared via a co-deposition in water/oil (w/o) phase method. The particle sizes of as-prepared samples were controlled by calcination temperature and calcination time, and the crystallinity of the samples enhances with increasing particle size. The luminescence properties of CaMoO4:Eu3+ microcrystals were studied with varying particle size. The results reveal that the intensity of emission spectra of the CaMoO4:Eu3+ samples increases with increasing particle size, and they have closely correlation with each other. It is the same with the luminescence lifetime. The luminescence lifetime of the CaMoO4:Eu3+ samples decreases from 0.637 ms to 0.447 ms with increasing particle size from 0.12 μm to 1.79 μm, respectively. This study not only provides information for size-dependent luminescence properties of CaMoO4:Eu3+ but also gives a reference for potential applications in high voltage electric porcelain material.
