Abstract
AbstractThe integration of 2D nanomaterials with silicon is expected to enrich the applications of 2D functional nanomaterials and pave the way for next‐generation, nanoscale optoelectronics with enhanced performances. Herein, a strategy for rare earth element doping is utilized for the synthesis of 2D WS2:Er nanosheets to achieve up‐conversion and down‐conversion...
