(a) Low temperature PL spectrum of SSCL phosphor. (b) Normalized PL spectra of greenish-yellow-emitting SSCL (solid line), yellow-emitting SSCL (broken line), and red-emitting CdSe QDs (dotted line).
PL spectra of CdSe core and CdSe/ZnSe core/shell QDs.
EDS spectra of (a) CdSe core and (b) CdSe/ZnSe. Insets are HR-TEM images of CdSe and CdSe/ZnSe, respectively (scale bar: 2 nm).
XPS spectra of (a) CdSe core and (b) CdSe/ZnSe core/shell.
(a) EL spectra and (b) CIE color coordinates of the CdSe/ZnSe QD-assisted SSCL-based WLED under various forward bias currents from 20 to 70 mA (○: CdSe/ZnSe QD-assisted SSCL-based WLED and △: YAG:Ce-based WLED).
