XRD OF SA/TOPO-capped ZnSe QDs.
(a) TEM image of SA/TOPO-capped ZnSe QDs; (b) SA/TOPO was removed from ZnSe QDs.
(a) Room-temperature PL spectrum of organics-capped ZnSe nanocrystals. The dotted lines were obtained by fitting a Gaussian curve. It indicates that the broad emission band consists of a blue emission band and a green-red emission band . The inset shows the organics-capped ZnSe QDs that produced white light when irradiated with a -He–Cd laser; (b) band diagram of SA/TOPO-capped ZnSe QDs.
Luminescence spectrum of a near-UV InGaN/white-emitting QDs WLED. The INGaN chip was operated at . The SA/TOPO-capped ZnSe QDs emitted white light when irradiated from InGaN irradiation. The CIE chromaticity is (0.38 and 0.41), which is in the white color region.
