Influence of hydrogenation of defects at the microcrystallite(MC)-glass interface on the nonlinear optics of CdSe-MC's

Using frequency doubled 35 ps pulses of a YAG laser to excite resonantly CdSe-MC's (R = 1.6 nm) embedded in glass, the absorption saturation and its kinetics are investigated at room temperature. A passivation of the MC-glass interface is realized by a hydrogen treatment of one sample. In the h...

Summary:Using frequency doubled 35 ps pulses of a YAG laser to excite resonantly CdSe-MC's (R = 1.6 nm) embedded in glass, the absorption saturation and its kinetics are investigated at room temperature. A passivation of the MC-glass interface is realized by a hydrogen treatment of one sample. In the hydrogenated sample a larger switching factor between the two transmission levels and a slower relaxation are observed supporting the assumption of carrier transfer into the glass matrix advanced by surface states.
