Study of the Spectroscopic Performance of Laser Produced CdTe, and CdTe:Ag Plasma

Abstract

This article, plasma parameters [((Te) electron temperature, (ne) electron density, (fp) Plasma frequency, (λD) Debye length, and (ND) Debye number], were studied by using a spectrometer that collects the laser spectrum produces cadmium telluride Plasma in different energies. As well as for CdTe: Ag for different card ratios. The electron temperature results for the CdTe range (0.699-0.738 ) ev also has an electron density of ( 2.867-4.430)∗ 1018Cm -3 was measured under vacuum up to 2.5 x 10-2 mbar. As well as for CdTe:AgTe range (0.738, 0.606) and ne range(4.430-4.691) )∗ 1018 Cm -3.The properties of CdTe and CdTe: Ag were determined throughoptical transmission method using the ultraviolet spectral spectrum inside range 190-1100 nm.
