Abstract: In the present work, undoped and Zn-doped CdTe nanoparticles are grown by chemical reduction method. The grown synthesized nanoparticles are characterized structurally by X-Ray diffraction (XRD) and transmission electron microscopy (TEM). The X-ray diffraction study confirmed the crystal structure of undoped and Zn-doped CdTe nanoparticles. Transmission electron microscopy study indicates the nature and size of the nanoparticles. The grown nanoparticles are characterized optically by Optical Absorption, Photoluminescence (PL) studies. The optical properties of the dye are also studied........ .
