Samples of ZnSe of the same lm thickness (320 nm) have been thermally evaporated on unheated quartz substrates using high purity powder. The prepared lms were subjected to pulsed laser annealing of two dierent powers. X-ray diraction studies revealed that the as-deposited samples were polycrystalline cubic (zinc-blende type) structure. As the annealing power increases, the crystallinity of ZnSe lms was improved with preferential orientation along the (111) direction parallel to the substrate surface. Microstructural characterizations have been evaluated using the DebyeScherrer formula. The absorption coecient as well as the energy gap for the asdeposited and the annealed samples were also reported.
