Abstract :
The lead selenide (PbSe) nanoparticles have been synthesized under ultrasonic/microwave co-irradiation. These PbSe nanoparticles were characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM) and DSC. In the new routes, pure PbSe phase was synthesized using elemental Se and lead acetate as starting materials and ethylene glycol as solvent under ultrasound of 25 kHz, 1500 W and microwave of 1000 W, 2450 MHz.
