Abstract :

Nanocrystalline cadmium selenide (CdSe) is a low bandgap material (Eg = 1.75 eV, at room temperature). II-VI semiconductor nanoparticles are presently of great interest for their practical applications in zero-dimensional quantum confined materials and for their applications in optoelectronics and photonics. In the present work, we have synthesized nanoparticles of CdSe using chemical method. Particle size has been reduced effectively by Ultrasound technique. This chemical method is very facile, inexpensive and less hazardous and ensures almost complete yield of the precursors while Ultrasound method yields finer particles. The CdSe nanoparticles were well characterized by powder X- ray diffraction (XRD) and Scanning electron microscopy (SEM). It is investigated that as synthesized powder has a hexagonal structure of CdSe with diameters of the particles in the range of 6-20 nm
