Transparent Glass Ceramics Doped by Chromium(III) and Chromium(III) and Neodymium(III) as New Materials for Lasers and Luminescent Solar Concentrators
Abstract
Transparent glass ceramics were prepared in the system Li2O-Al2O3- SiO2, MgO-Al2O3-SiO2 and ZnO-Al2O3-SiO2 using TiO2, ZrO2 and P2O5 as nucleators. The major crystalline phases in these samples were spinel, gahnite, beta-quartz solid solutions and petalite-like-phase. These were doped with Cr(III) and spectroscopic properties measured. The efficiency of luminescence in these glass ceramics was very high compared to glass samples, viz. ca. 50% in beta-quartz, 75% in petalite-like-phase and close to unity in gahnite. For practical purposes the results may be important in designing luminescent solar concentrators and lasers based on Cr(III).
