研究目的
Investigating the influence of Sn2+ ion on structural, morphological and optical characteristics of Cd0.92xZn0.1SnxS (0 ￡ x ￡ 0.06) quantum dots for optoelectronic device fabrication.
研究成果
Cd0.9-xZn0.1SnxS (0 B x B 0.06) QDs exhibited cubic structure with increased particle size due to Sn substitution. UV–visible absorption peak intensity increased, and blueshift was observed in band gap values. PL emissions near 400 nm and 495 nm were attributed to surface defects. These materials are suitable candidates for optoelectronic device fabrication.
研究不足
The study is limited to the synthesis and characterization of Sn, Zn-dual-doped CdS QDs via chemical co-precipitation technique. The potential for optimization in synthesis parameters and application in devices beyond optoelectronics is not explored.
