Semicnoductor nanoparticles are promising candidates for optoelectronic devices, sensors and display devices due to their size dependent unique properties which can be varied. ZnS a class of wide baudgap II-IV semiconductor (3.65 eV) is a novel class of luminescent I Material that exhibits excellent physical and chemical properties when reduced to nanodimensions. A facile chemical route of synthesis of pure ZnS and :triethylamine capped ZnS is reported. The structural and phase information is obtained from XRD studies. The optical properties of the prepared samples were measured using using UV-VIS. and photaluminescence spectroscopies. The UV-VIS studies shows a blue Shift, compared to its bulk counterpart. The photoluminescence signal intensities of doped ZnS shows enhancement compared to I undoped samples. The FTIR studies confirm the presence of triethylamine in the synthesized product. The HRTEM images shows sheet like-morphology When doped with triethylamine. In this paper we report a general strategy for the synthesis of functional nanomaterials.
