Luminescence Properties of ZnS:Mn Quantum Dots

Authors: Xiao Song Zhang, Lan Li, Dong Qing Dong, Zhi Wang, Xiao Yi Dong

Abstract: ZnS:Mn quantum dots were prepared in the aqueous medium from readily available precursors. The construction, morphology and luminescence properties of the ZnS:Mn quantum dots were evaluated by XRD,TEM and photoluminescence spectra. The blue and orange emission of the ZnS:Mn quantum dots excited by a 532nm picosecond laser were discussed.

Luminescence Properties of ZnS:Er Quantum Dots with NIR Excitation

Authors: Xiao Song Zhang, Xiao Yi Dong, Gui Yun Kai, Dong Qing Dong, Yan Fang Zhang, Zhi Wang

Abstract: ZnS:Er quantum dots were prepared in the aqueous medium from readily available precursors. The construction, morphology and luminescence properties of the ZnS:Er quantum dots were evaluated by XRD,TEM and photoluminescence spectra. Furthermore, the 1590 nm emission of the ZnS:Er quantum dots excited by a 785.0 nm NIR laser were discussed.
