Abstract: Present study describes a simultaneous and highly reproducible, large-scale, one-pot, template free synthesis of nearly homogeneous and blue luminescent CdSe nanoparticles (NPs) in a single reaction at 50°C by wet chemical method. The method is simple, inexpensive and ensures almost complete utilization of the precursors. The product was well characterized by X-ray diffraction, UV-Vis. spectroscopy, Fourier transform infrared spectroscopy and Transmission electron microscopy. X-ray diffraction pattern indicates that CdSe NPs possess a Wurtzite (Hexagonal) structure. Systematic particle size dependent ‘blue shift’ is observed in optical absorption edge. Transmission electron microscopy showed that the particles diameters are in the range of 5 – 8 nm.
