Paper presents the influence of thermal treatment on structural and optical characteristics of Sb0.5ZnTe thin film. Alloy of Sb0.5ZnTe has been prepared through traditional and economical melt quenching technique and thin films of prepared alloy was deposited onto glass substrate by thermal evaporation method at pressure of 10–6 Torr. The antimony doped films were annealed for 2 h at three different temperatures ranges (373 K, 393 K and 413 K). Structural characterization of as prepared and annealed film was done by XRD technique and it was found that annealing improves the film crystal structure. UV-Vis spectrophotometer facilitates optical analysis of Sb0.5ZnTe film in wavelength range of 400–1000 nm. It was observed that band gap Eg of the Sb doped film increased while absorption coefficient (α) decrease with increase in heating temperature. These changes in optical properties were explained in terms of defect states.

ABSTRACTThis paper deals with the application of some recently developed evanescent waveoptical techniques for the characterization of novel macromolecular host-guest systems. In particular, surface plasmon- and guided optical wave-spectroscopies and -microscopies are used to determine the linear and nonlinear optical properties of these materials in thin film form.

A study has been conducted on the characterization of optical properties of thin films from lidah mertua (Sansevieria trifasciata) with dip coating method. The dip coating method was applied with different temperature and different time immersion treatments. The measuring variables in the manufacture of this thin film were tested based on the optical properties of their absorbance value of the extract and the thicknessof thin film. The absorbance spectral of extraction pigments were measured using UV-Vis in the wavelength range 350 nm to 700 nm. The results of the measurements showed that the extract of the S. trifasciata has high absorbance. Beside that, the minimum coating thickness is produced by a concentration of 12.5% with a 5 minute immersion time of 520 nm.

The structural, electronic, magnetic, and optical properties of AuAl 2, AuGa 2, AuIn 2, and PtGa2 are reviewed. These experimental results are compared with the values of the density of states at the Fermi level derived from band-structure calculations. The so-called “ AuGa 2 dilemma” and the controversial positions of the Au 5d bands in AuAl 2, AuGa 2, and AuIn 2 are discussed. The physical properties of PtGa 2 are summarized and compared with those of the Au intermetallic compounds. Recent researches on the growth and characterization of these compounds in thin-film form are also presented.
