Abstract

Color center formation was studied in vacuum sintered Nd_3x Y_3-3x Al₅ O₁₂ transparent ceramics. The primary color centers were F- and F+ -centers as evidenced by optical absorption in the 250-400 nm wavelength range and the presence of an electron spin resonance (ESR) line at g=1.9977. Annealing in air at 1600 °C for 10 h reduced the number of color centers to below the detection limit of ESR. Color center formation is controlled by oxidation and reduction of Fe2+/3+ impurities.
