Abstract

In this work, the bismuth silicate (Bi4Si3O12, BSO) microcrystalline were synthesized via a solid state reaction. The structure and the lattice constant of BSO microcrystalline were studied by the X-ray diffraction patterns (XRD). The emission and excitation spectra of BSO microcrystalline doped with 0.05 mol% of trivalent rare-earth and transition metal element ions were also investigated. The research results revealed that the radius of rare-earth ions could influence the light output of BSO microcrystalline and the luminescence intensity of Eu3+-doped microcrystalline was significantly enhanced. The results showed that the radius of doped rare earth ions was an important factor for affecting the luminescence intensity of BSO microcrystalline. It has an important guiding significance for the research of luminescence properties of BSO crystal doped with rare earth and the performance of dual-readout, as well as has important reference value for rare earth doped other crystals research..
