Thermal and optical characterization of Zn XCd 1− XS embedded in a zeolite host

Abstract

Ternary compounds Zn X Cd 1− X S (0≤ X≤1) embedded in mordenite zeolite host are studied by using Photoacoustic techniques and X-ray diffraction. We found the thermal diffusivity, thermal effusivity and band-gap as a function of the X parameter. This study shows a strong dependence of thermal and optical parameters with the X value (Zn% concentration). At low X values, we found a peak in the thermal parameters. From Photoacoustic Spectroscopy (PAS), we observed a parabolic behavior of the band gap as a function of X. The X ray diffraction patterns shows that sintered mordenite host structure was maintained with the growth of the ternary compound, however the intensity of the peaks were sensitive to the X value of these compounds. Electron Diffraction Scattering (EDS) measurements were used to determine the X value of our samples.
