a PL spectra of InP/ZnS QD film (untreated) (black line) and QDs in colloidal solution (red line). Absorption spectrum of the colloidal QDs in colloidal solution (blue line). The insert picture is the structure of InP/ZnS core-shell QDs. b Peak fitting of PL spectra of InP/ZnS QD film (untreated) (black line). The green and blue are the fitting curve of this spectra, which are named A and B. The insert picture is the structure of InP/ZnS QD films
