Abstract

Transparent ZnO–Ga 2 O 3 –SiO 2 glass-ceramics embedded with Co 2+ :ZnGa 2 O 4 nanocrystals were fabricated by the sol–gel method. X-ray diffraction, infrared spectroscopy and high-resolution transmission electron microscopy showed that the resulting material is composed of an amorphous silicate network and single-crystalline ZnGa 2 O 4 particles. Analysis of the absorption and luminescence properties indicates that Co ions are trapped in the crystalline phase and located in the tetrahedral sites in ZnGa 2 O 4 nanocrystals. The crystal field parameter D q of 418 cm −1 and the Racah parameters B of 761 cm −1 and C of 3424 cm −1 were determined for tetrahedral Co 2+ ions.
