dc.description.abstract | Photoinduced charge-transfer dynamics between CdSe quantum dots (QDs) possessing varying monolayers of ZnS and hole scavengers such as phenothiazine (PT) and N- methylphenothiazine (NMPT) were investigated for optimizing the shell thickness of core - shell quantum dots. Spectroscopic investigations indicate that phenothiazine binds onto the surface of bare CdSe QDs, resulting in the photoluminescence quenching, and two monolayers of ZnS prevent the electron -transfer process. Methodologies presented here can provide quantitative information on the optimum shell thickness of core - shell QDs, which can suppress the undesired electron transfer and provide maximum luminescence yield. | en_US |
