P. Thoen et al., TIME-RESOLVED PHOTOLUMINESCENCE IN YBA2CU3O6.4 AND BI2SR2CA1-ZLUZCU2O8, Physical review. B, Condensed matter, 49(1), 1994, pp. 694-697
We report on the spectral investigation of the time-resolved photolumi
nescence in insulating YBa2Cu3O6.4 (YBCO) thin films and Bi2Sr2Ca1-zLu
zCu2O8 (BSCLCO) single crystals. The characteristic decay times of the
photoexcited states in YBCO are two orders of magnitude longer than i
n BSCLCO, and have a different dependence upon the emission wavelength
. These observations provide insight into the static photoinduced phen
omena recently found in YBCO.
