摘要：

The optical spectroscopy of YAG:Ni, Zr(Si) and GSGG:Ni, Zr(Si) crystals is presented. Absorption bands of Ni2+ ions in octahedral and tetrahedral coordinations are observed. Comparison of experimentally observed and predicted energy levels for Ni2+ in both sites is made and the parameters Dq, B and C are determined. Luminescence transitions in the near-infrared, green and red are investigated and assigned to the 3T2→3A2, 1T2→3A2 and 1T2→3T2 transitions of octahedral Ni2+ ions. Photocoloration of the crystals indicate that part of the dopant tetrahedral nickel ions turn into the trivalent state. The absorption spectrum of Ni3+ ions in GSGG:Ni is analyzed. © 1990.
