摘要	The spectral properties of the Cr3+ broad emission band in A(3)M(2)Ge(3)O(12) : Cr(A = Cd2+ ,Ca2+ ;M = Al3+ ,Ga3+,SC3+) germanate garnets at room temperature are reported for the first time. In the order of Al3+-->Ga3+--> SC3+ and Cd2+ -->Ca2+ ions which occupy the octahedral and duodeahedral sites, respectively, R-NIR broad emission band of T-4(2) -->(4)A(2) level transition, emission peak, and the spectral long wavelength and short wavelength sides of Cr3+ Shift to long wavelengths having lower energy. The reason is that the crystal field strengths in the octahedral decrease,while the cation ionic radii in the A(3)M(2)Ge(3)O(12) system garnets increase gradually. The R-NIR emission intensity of Cr3+ is increased with some SC3+ ions substitution for Al3+ or Ga3+ ions in octahedral sites.
