摘要：
The temporal characteristics and temperature dependence of the Gd3+ to Cr3+ energy transfer in Cr3+:GSGG are presented. Following pulsed excitation of the S-8(7/2) --> P-6(7/2) transition in Gd3+, the risetime of the resulting Cr3+ fluorescence was used to determine the Gd3+ to Cr3+ energy transfer rate. The results indicate a rapid energy migration among the Gd3+ ions followed by a Gd3+ to Cr3+ energy transfer step over a single fixed distance.
