- Abstract
- In this work, PbS QDs were precipitated in the glass containing sodium strontium silicate (Na2SrSi2O6) nanocrystals. Tunable absorption and photoluminescence of PbS QDs in the range of 1700-2200 nm were achieved through thermal treatment. Increased heat-treatment duration and temperature would induce the formation of Na2SrSi2O6 nanocrystals. The results from absorption and photoluminescence spectra and X-ray diffraction patterns indicated that PbS QDs acted as nucleating agents for Na2SrSi2O6 nanocrystals and facilitate their formation. The high resolution transmission electron microscopy analysis confirmed that PbS/Na2SrSi2O6 core/shell nanocrystals were formed in the glass. (C) 2016 Optical Society of America
