Intensely emitting CdTe nanocrystals retained initial photoluminescence efficiency in sol–gel derived Si1-xZrxO2 glass

Abstract  Emitting CdTe nanocrystals (NCs) were embedded in pure glass matrices (Si1-xZrxO2, x≤0.15) using a controlled sol–gel method, where the pre-hydrolyzed condition, the molar ratio of Zr/Si, the gelation time, the pH,
