Optical parameters of ZnSe chalcogenide nanostructures

Abstract

Laser induced time resolved photoluminescence was used to calculate various optical parameters like Einstein's spontaneous coefficients, Einstein's stimulated coefficients, oscillator strengths, dipole moment and integrated cross-section of these chalcogenide nanostructures. ZnSe doped nanoparticles has been fabricated using chemical precipitation method and steric hindrance is given by polyvinylpyrrolidone. The size and morphology of the nanostructures is determined by the XRD, TEM and SAED. ZnSe nanostructures show weak electric dipole visible transitions due to the perturbations of added dopants. These optical parameters are very useful in electronics, computing, optics, biotechnology, medical imaging, medicine, drug delivery, structural materials, aerospace, energy, etc. © 2021 Elsevier B.V., All rights reserved.
