Fig. 1: DUV—NIR-II broadband PD.

a The detection range for the commercial GaN PDs, Si PDs, InGaAs PDs, and this work. b Schematic of a broadband PD configuration. c Absorption and emission spectra of PbS QDs. Inset is the image of PbS QDs. d Energy level diagram of QC–LC. e Absorption spectra of QC–LC and CsPbI3:Ho3+—PbS QDs, and emission spectra of QC–LC
