The thermoluminescence (TL) properties of CVD diamond film irradiated with b rays and illuminated with UV and visible light (200–450 nm) have been studied. The film (23mm) was grown for 47 h on monocrystalline silicon. The TL glow curves are similar for b irradiation and short wavelength UV light. The b dose response curves and UV light time response curves exhibit linear–supralinear–sublinear ...

Radiation effects of photon irradiation in Ytterbium-doped silica optical fibers are still much less explored despite their importance in space-based application as radiation dosimetry. This study investigates and compares the thermoluminescence glow curve, response, linearity and sensitivity of Ytterbium-doped SiO2 optical fibers with that of TLD-100. Samples are placed in solid phantom and ir...

The dependence of the shape of the glow curve of LiF:Mg,Ti (TLD-100) on ionisation density was investigated using irradiation with (90)Sr/(90)Y beta rays, 60 and 250 kVp X rays, various heavy-charged particles and 0.2 and 14 MeV neutrons. Special attention is focused on the properties of high-temperature thermoluminescence; specifically, the behaviour of the high-temperature ratio (HTR) of Peak...

Despite a widespread interest in the warm glow model [Andreoni (1989,1990)], surprisingly most attention focused on the voluntary contribution equilibrium of the model, and only very little attention has been devoted to the competitive equilibrium. In this paper, we introduce the notion of competitive equilibrium for a warm glow economy [Henceforth, warm glow equilibrium]. Then, we establish (a...

We introduce Glow Clustering, a clustering technique inspired by the physics of light and the images of spiral galaxies. We discuss the genesis, design, and implementation of Glow Clustering. We evaluate Glow Clustering on test datasets and a well-known standard dataset. Finally, we attempt to describe the characteristics of Glow Clustering, giving some insight into the context of use where Glo...

Sr2SiO4:%3Nd3+ was synthesized and its structural characterization made via XRD technique. The results indicated that had Pmma (62) space group (PDF: 00-039-1256) in the orthorhombic crystal system. Luminescence thermoluminescence (TL) properties of Sr2SiO4:%3Nd3 investigated detail. Computerized glow curve deconvolution methods used for to determine kinetic Sr2SiO4:%3Nd3+. TL showed Sr2SiO4:Nd...
