Abstract

Alloys of Se100-xSb10-xAgx (x=2, 4, 8) glassy system are obtained with rapid quenching. Calorimetric studies have been performed at different heating rates under non-isothermal conditions. Well defined endothermic and exothermic peaks are obtained at glass transition (Tg) and crystallization temperatures (Tc). In the present study, the glassy alloys are found to have double glass transition and crystallization temperatures. From the dependence of the glass transition temperature on the heating rate β, the activation energy of glass transition has been calculated on the basis of Moynihan and Kissinger models. The value of (Tc–Tg) and stability parameters have also been calculated for each composition for both the phases. Value of Eg is found to be decreased with increase in concentration of Ag. The values of (Tc-Tg) is highest for the sample with 8 at % of Ag. Activation energy of crystallization (Ec) has also been calculated using the well-known Kissinger’s relation, Matusita–Sakka theory and the method of Augis and Bennett. A good agreement has been found in all the three methods. The activation energy of crystallization is found to decrease with increasing concentration of Ag.

Abstract

In this work, the mechanism and principle of optical laser microscope (OLM) which works on the principle of light reflection that used in many applications were presented. Image of silicon wafer that obtained from OLM was enhanced and analyzed using image processing algorithm. The used algorithm was designed using MATLAB 10.0.The output images from RLOLM were compared with images of ordinary microscope.

Abstract

In this research, thin films of ZnO of thickness 5200ű30 prepared using chemical spray method. The films deposited on Crown glass substrates Optical studies show that in these films the electronic transition is of the direct transition type. The optical energy gap for the films of as deposited and for those heat treated for an hour at different temperatures is estimated to be in the range 3.05-3.2 eV. Results analysis exhibits the dependence of optical energy gap on the temperature of heat treatment.

Abstract

In this paper, we report the inorganic-organic hybrid junction synthesized on ITO glass substrate, which was consisted of an n-type ZnO nanorods (NRs) grown by low-temperature aqueous chemical growth method and a p-type Polyfluorene (PF) organic film fabricated by spin-coating. The results indicate that densely and uniformly distributed ZnO nanorods were successfully grown on the PF layer. The thickness of the PF layer plays a dominant role for the current–voltage (I-V) characteristic of the ZnO NRs/PF inorganic-organic hybrid junction device, and a p-n junction with obviously rectifying behavior was achieved with optimal PF layer thickness. The photoluminescence (PL) spectrum covering the broad visible range was obtained from the n-ZnO nanorods/p-polyfluorene (PF) structure, which was originated from the combination of the PF-related blue emission and the ZnO-related deep level emission.
