Optical Investigations of CdSe1-x Tex Thin Films
Get PDFThe alloys of CdSe1-xTex compound have been prepared from their elements successfully with high purity (99.9999%) which mixed stoichiometry ratio (x=0.0, 0.25, 0.5, 0.75 and 1.0) of (Cd, Se and Te) elements. Films of CdSe1-xTex alloys for different values of composition with thickness(0.5?m) have been prepared by thermal evaporation method at cleaned glass substrates which heated at (473K) under very low pressure (4×10-5mbar) at rate of deposition (3A?/s), after that thin films have been heat treated under low pressure (10-2mbar) at (523K) for two hours.
The optical studies revealed that the absorption coefficient (?) is fairly high. It is found that the electronic transitions in the fundamental absorption edge tend to be allowed direct transition. It was also found that the optical energy gap vary non-linearly with composition (x) and have a minimum value at x=0.5 and increases after heat treatment.
It is found that the optical constants vary non-linearly with composition, and the behavior inverse at x=0.5, and affected by heat treatment. The behavior of ?1 is similar to the behavior of n, while the behavior of ?2 is similar to the behavior of k

Epoxy plates have been made in the laboratory by mixing epoxy resin (A) with, hardener (B) in ratio (A: B) = (2:1), so they made (6) plates of different thickness about (0.95-5.8)mm .
The optical properties have been studied like (absorption, transmittance, reflectance, energy gap and fluorescent) also the optical constant were found including (absorption coefficient, extinction coefficient and refraction index) for all plates.
The results have shown that by increasing the thickness of plates the absorption intensity increase; at plates thickness (0.95-5.8)mm the absorption intensity were ، (0.20,0.69) respectively , and since absorption peak for epoxy occur in ultraviolet region and exactly at wavelength (330 nm) and energy gap (Eg=3.59(eV)) ; so the plates have transmittance about (60-92)% in visible region . The refraction index for Epoprimer epoxy is (n=1.3) and its reflectance is (R=20 %) at wavelength (330 nm) .
While the fluorescence spectrums that result form shifting absorption spectrum (stoke shift) for epoxy plates it differ according to the used plate’s thickness. Where the shift increases toward longer wavelengths the (red shift) with the increase in plates thickness as the results show; so at plate thickness of (0.95, 3 ,5.8)mm the fluorescence spectrum shift was (100,131,140)nm respectively .
