Band‐gap shift in CdS semiconductor by photoacoustic spectroscopy: Evidence of a cubic to hexagonal lattice transition
The band‐gap energies of the CdS semiconductor are obtained by a photoacoustic spectroscopy (PAS) technique over a range of temperature of thermal annealing (TTA), in which the evolution of theExpand

Photodegradation of gaseous C6H6 using CdO+CdTiO3 and TiO2 thin films obtained by sol–gel technique
Abstract In this work, TiO 2 and CdO + CdTiO 3 multicomponent oxide thin films growth was performed with different Ti/Cd ratios (0, 0.20, 0.49, 0.60, 0.65, 0.70 and 1) by the sol–gel route in orderExpand
