研究目的
Investigating the enhancement of photoluminescence intensity in perovskite CsPbBr3 quantum dots film by plasmonic Au nanorods.
研究成果
The incorporation of Au nanorods into CsPbBr3 quantum dots film significantly enhances the photoluminescence intensity due to the localized surface plasmon resonance effect. This study provides a foundation for further research into the application of plasmonic enhancement in optoelectronic devices.
研究不足
The study focuses on the enhancement of photoluminescence intensity but does not explore the potential applications in devices in depth. The optimization of the film quality and the exploration of other metal nanostructures for further enhancement are areas for future research.
