Luminescence of colloidal CdSe/ZnS nanoparticles: high sensitivity to solvent phase transitions

Abstract

We investigate nanosecond photoluminescence processes in colloidal core/shell CdSe/ZnS nanoparticles dissolved in water and found strong sensitivity of luminescence to the solvent state. Several pronounced changes have been observed in the narrow temperature interval near the water melting point. First of all, the luminescence intensity substantially… (More)
