An intermolecular charge and electron transfer processes in photoluminescent ZnS- L-Cysteine: core-shell Nanoparticles (NPs) extend highly sensitive and variable valence at the core (ZnS)-shell (L-Cysteine) interface primarily due to an extensive mixing of materials frontier orbital (i.e. covalency). Water soluble, ZnS- L-Cysteine: core-shell photo luminescent NPs achieved by straight forward micellar route that is thrust area of research in nanoscience for the control particle size and remarkable properties through chemical co-precipitation method. In the paper we studied, the synthesis of CTAB capped ZnS NPs as well ZnS- L Cysteine: core-shell NPs and examined by their composition, particle size and optical and luminescent properties. The NPs stabilized with CTAB and demonstrated the regular ZnS blue emission on recombination over ZnS band-crevice from shallow electron traps at 490 nm. The onset of the absorption was 80 nm blue shifts moved from 345 nm (bulk) to 265 nm, showing a quantum size impact. Quantum mechanical effect of light applied especially in semiconducting NPs through optoelectronic orbital model, which detect and control the light through electronic devices.

Developing new smart materials and tracking their structural potential have been in focus for curing disease and other applications such as catalyzing biomolecules like proteins and selective bioremediation of toxic metals, dyes, pesticides have been thrust areas of research in the field of materials and biomaterials sciences. Since materials are most important need of the society which develops somewhere food, drug, fuel, protective cover, defense materials, fire resistant and acoustic mechanism, UV sensitive, UV absorbing, solar radiation trapping activities. In this context, the dendrimers have been considered as ideal and smart materials to be applied for wider applications and directly, indirectly or catalyze modulator and many others. Thus, the dendrimers act as smart materials and the synthesis of such architectural and potential molecules is being considered as a new thrust area for multitasking materials with better activities to catalyze chemical and biochemical processes. The multifunctional materials of multipurpose uses with several dendrimeric branching, having innumerable binding sites and are in high demands for their drug binding, loading potential and bio coatings.
