dc.description.abstract Herein we report the first time use of a hue parameter of HSV (Hue, Saturation and Value) color space - in combination with chromaticity color coordinates - for exploring the complexation induced luminescence color changes, ranging from blue to green to yellow to white, from a non-luminescent Fe-doped ZnS quantum dot (QD). Importantly, the surface complexation reaction helped a pre-synthesized non-luminescent Fe-doped ZnS QD to glow different luminescence colors (such as blue, cyan, green, greenish-yellow, yellow) by virtue of the formation of various luminescent inorganic complex (using different external organic ligands). While the simultaneous blue and yellow emitting complex formation on the surface of non-luminescent Fe-doped ZnS QD led to generation of white light emission, with hue mean value of 85, and chromaticity of (0.28,0.33). Furthermore, the surface complexation assisted incorporation of luminescence properties to a non-luminescent QD not only overcome their restricted luminescence based applications such as light emitting, biological and sensing applications but also bring newer avenues towards unravelling the surface chemistry between QD and inorganic complex and the advantage of having inorganic complex with QD for their aforementioned useful applications.
