Polycrystalline thin films of CdTe grown on glass/SnO[sub 2]/CdS substrates are studied using X-ray diffraction, atomic force microscopy, and time resolved photoluminescence decay techniques. CdS films were deposited by chemical solution. CdTe films were grown by close-spaced sublimation at substrate temperatures between 475--625 [degree]C. CdTe thin films deposited at temperatures higher than 525 [degree]C show preferential orientation in the [l angle]111[r angle] direction. The Grain size of the films increases with substrate temperature and the films are faceted for all the temperatures. The PL decay constant increases with substrate temperature up to 575 [degree]C for as-deposited films on soda-lime substrates. Films on borosilicate substrates show an increase up to the highest temperature used (625 [degree]C). There is systematic increase in the PL decay constant after CdCl[sub 2] heat treatment, and the range of values is 1--1.5 nsec for soda-lime samples and 1--2 nsec for borosilicate samples.
