Advantages

Dual carrier transfer pathways

Besides interfacial energy transfer, small-sized Au nanocrystals introduce an additional charge transfer channel, enhancing carrier utilization.

Size-tunable carrier dynamics

As the size of Au nanocrystals decreases, carrier generation and relaxation processes accelerate, enabling tuning of device response time via Au size selection.

Applications

• perovskite optoelectronic devices：Enhance light absorption and carrier separation to improve device efficiency
• plasmonic photodetection：Utilize plasmonic enhancement to boost photoresponse and speed up photocurrent generation
• nanoscale optoelectronics：Serve as carrier management unit for precise control of interfacial charge transfer dynamics
