The effect of chemical treatment in CdCl2 on the compositional changes and defect structures of potentially useful ZnS solar cell thin films prepared by vacuum deposition method was studied using the complementary Rutherford backscattering (RBS) and Thermoluminesence (TL) techniques. A series of electron and hole traps are found in the various as deposited samples studied. After treatment, pert...

Silicate minerals are therefore isolated from the foodstuffs, mostly by a density separation step. In order not to obscure the TL, the isolated silicate minerals should be as free of organic constituents as possible. A first glow of the separated mineral extracts is recorded (Glow 1). Since various amounts and/or types of minerals (quartz, feldspar etc.) exhibit very variable integrated TL inte...

Pure and copper doped ZnS nanoparticles in powder form were prepared by wet chemical route method by using thioglycerol as a capping agent. The XRD studies indicate that the samples are cubic in nature. The thermoluminescence (TL) behavior of pure and copper doped ZnS has been studied for fixed 10 min UV exposure time; TL glow curve shows a single peak at 165.1°C and 184.3°C temperature respect...

In the early years, the routine personal dosimetry at the Nuclear Research CenterNegev was performed by using photographic films. In 1975, the TLD method was introduced. The routine personal dosimetry was performed by using the LiF:Mg, Ti phosphors (G-1 cards), and employing an automatic Harshaw 2271 reader. The heating of the phosphor was performed by a hot finger, and the integral light outpu...

The family replication problem is addressed in the context of the dual standard model. The breaking of a simple grand unified group to [Glow × H1 × H2 × H3]/Z 3 5 and then further to Glow, produces a spectrum of stable monopoles that fall in three families each of whose magnetic quantum numbers correspond to the electric charges on the fermions of the Standard Model. Here Glow = [SU(3)×SU(2)×U(...

The thermoluminescence (TL) glow curves of UV irradiated PAAm-PVA polyblend have been studied. The experimental glow curves show the presence of two peaks with glow peak temperatures at 373K and 479K. The values of activation energy and frequency factors are determined by employing computer simulation. Most of the TL glow curves obey non first order kinetics. The results obtained by using TL ex...

Most surfaces reflect light from external sources, but others emit light: they glow. Glowing surfaces are often a sign of an important feature of the environment, such as a heat source or a bioluminescent life form, but we know little about how the human visual system identifies them. Previous work has shown that luminance and luminance gradients are important in glow perception [1,2]. While a ...
