摘要
Yttrium gallium garnet (YGG) submicrocrystals having 80 nm average diameters doped with Cr3+ (0.1-40%) were synthesized by the citrate method. Pure cubic garnets were obtained in wide range (0.1-15%) of dopant concentration. Chromium ions replace Ga3+ at the octahedral sites and experience an intermediate or weak crystal field, depending only on Cr3+ concentration. The weak crystal field is observed when the dopant concentration exceeds 3%. The origin of such behavior is discussed.
