Abdullah, Hanaa	Effect of Annealing Temperature and Thickness on the Structural and Optical Properties of CdSeThin Films	2017	11	.pdf	application/pdf	4165	213	63	The optical measurements indicated that CdSe thin films have allowed direct optical energy band gap, and it increases from (1.77- 1.84) eV and from (1.6-1.65)eV with the increase in temperature from (R.T-673)K for thicknesses. It has high efficiency of radiative recombination, high absorption coefficient, high photosensitivity, direct band gap corresponding to a wide spectrum of wave lengths from ulttraviolet to infrared regions[9].The properties of materials prepared by different methods are critically dependent on the nature of preparation technique and subsequent heat treatments like annealing in air, vaccum or different gaseous environments etc[10].A variety of techniques have been used to prepare CdSe thin films including thermal evaporation[11-13],electron beam evaporation[14],chemical bath method[15] and molecular beam epitaxy[16].	cache/iajs-189.pdf	txt/iajs-189.txt
