Sb_2S_3 Nanocrystals in glass

摘要

In this work conventional quench method was adopted to fabricate Sb_2S_3 nanocrystals in glass. The glass composition was optimized for proper glass host matrix to grow semiconductor Quantum dots. The systematic compositional variation of network former and network modifier oxides can further reveal the effect of matrices on the formation of stibnite quantum dots. The dot sizes and their distributions were modified by heat treatment of glass samples in the temperature range from 500°C to 700°C. X-ray diffraction studies were carried out for size distributions and nanoparticles with size ranging from 25nm to 80nm were obtained. The size distribution of Sb_2S_3 nanoclusters was later confirmed by using transmission electron microscopy. Quantum dots so grown were further characterized by optical absorption and Photoluminescence spectroscopy.
