The present research paper reports the preparation and characterization of nano particles of Tin Selenide (SnSe) by chemical precipitation method in deionized water. Chemical composition of grown powder is studied with the help of EDAX. Nanostructures of the prepared SnSe particles have been characterized through XRD, TEM, UV-VIS-NIR spectroscopy techniques. The X-ray diffraction studies indicated the formation of SnSe nanoparticles with orthorhombic phase and average particle size determined by Scherrer’s formula has been found to be 9.96 nm suggesting the formation of SnSe quantum dots. The prepared nanostructures have been also analyzed by TEM. The value of the measured optical band gap has been utilized to calculate the particle size (10.13 nm). Dielectric properties of tin selenide nano particles are investigated. It showed strong frequency and temperature dependence of capacitance, dielectric loss, real and imaginary part of dielectric constant over the frequency and temperature ranges of 100Hz- 1MHz and 300-420 K, respectively.
