Abstract

The synthesis, surface ligand stripping, and infrared optoelectronic device application of NaYF₄:Yb,Er–MoS₂ nanocomposites are reported. NaYF₄:Yb,Er–MoS₂ film shows an unusual negative infrared photoresponse after SOCl₂/DMF treatment, which exhibits more than two times the photoresponsivity of pure NaYF₄:Yb,Er, showing great potential for the development of novel infrared optoelectronic devices.
