摘要:

The nonlinear refractive indexn2is reported for quantum‐confined CuCl microcrystallites in borosilicate glass near theZ3excitonic resonance. Induced index changes were estimated using Kramers–Kronig analyses of absorption bleaching data from 370 to 388 nm. The nonlinearity was found to increase with increasing particle radius over the range 22 to 34 A˚, in agreement with theoretical predictions.
