研究目的
Investigating the effect of Ag/rGO on the optical properties of plasmon-modified SnO2 composite and its application in self-powered UV photodetector.
研究成果
The study successfully demonstrated that Ag/rGO incorporated into SnO2 nanorods enhances the performance of self-powered UV photodetectors through plasmon-enhanced UV-absorption and effective suppression of charge recombination. The optimized device showed high photocurrent, fast response time, and good reproducibility.
研究不足
The study focuses on the synthesis and characterization of Ag/rGO-SnO2 composites and their application in UVPDs. Potential areas for optimization include the concentration of Ag/rGO and the scalability of the fabrication process.
