摘要:	In this thesis, we report the photoluminescence and optical nonlinearity of water-soluble PVA-capped CdSe nanoparticles with high quantum yield (around 68%). Luminescence properties of water-soluble CdSe nanoparticles were studied using time-integrated and time-resolved photoluminescence (TRPL) measurements at room temperature. We observed the photoactivation of CdSe nanoparticles induced by ultrafast laser pulses. By using the Z-scan measurement technique, we measured two photon absorption coefficient of water-soluble CdSe nanoparticles.
