Novel ultra-wideband fluorescence material: Defect state control based on nickel-doped semiconductor QDs embedded in inorganic glasses

In recent years, the development of an environmentally friendly quantum dots (QDs) embedded luminous solid by a simple method has attracted considerable attention.In this study, semiconductor ZnS QDs were successfully prepared in an inorganic matrix of amorphous glass, which gibson sg fireburst yielded beneficial broad-band emission in the long-wavelength region of the visible range.The strong red emission belonged to the defect state energy level of the ZnS QDs, which could be enhanced by incorporation of nickel ions into the fixed matrix to regulate the defects state.The novel material had a small self-absorption, wide excitation and emission ranges, and thus potential applications in light-conversion devices, luminescent x515ea-bh55-cb solar concentrators, and solar cell cover glasses.
