Abstract :
Summary form only given. We present optical gain measurements in quantum dots (QDs) with nanosecond nonresonant excitation using the variable-stripe-length method. The QDs, fabricated by sol-gel process, are embedded in a sodium borosilicate glass with a CdS concentration of about 6 wt%. We investigate the photoluminescence decay dynamics using femtosecond excitation at 310 nm and streak camera detection.
