摘要：

We describe a facile sol-gel process using a silane coupling agent to encapsulate photoluminescent CdTe nanocrystals. An amino-containing matrix and CdTe NCs stabilized by thioglycolic acid were found to be the best combination to prepare the glass because of the interaction between amino and carboxyl groups. The process of synthesis was optimized to prevent nanocrystals from agglomerating. The optical absorption and luminescent spectra of CdTe nanocrystals remained unchanged after being embedded into the glass matrix. Multi-color nanocrystals embedded in glass had the photoluminescence efficiencies up to 41%, which were similar to those of starting nanocrystals in solution. The nanoparticles embedded in glass had excellent stability over time and with heat treatment. (C) 2004 Elsevier B.V. All rights reserved.
