Luminescence and scintillation characterization of Silver doped KCl single crystal grown by Czochralski technique for photonic applications
Authors
Abstract:
In this study, the scintillation and optical properties of pure and silver doped potassium chloride (KCl:Ag) single crystals were reported. Pure and doped KCl bulk single crystals with a good optical quality and free from cracks were grown from the melt using Czochralski technique. Different analysis methods were used to study the optical and scintillation properties of the grown crystals. The XRD, EDX and SEM results confirmed the formation of KCl compound. The UV excitation, X and gamma rays were employed to evaluate the scintillation and optical properties of the synthesized samples. The X-ray induced luminescence spectrum of doped crystal showed the prominent blue emission at 400-460 nm wavelength region. Also, the thermoluminescence response of doped sample showed a strong TL glow peak at 200 and proper linear ranges as a function of dose making it a promising candidate for dosimetry and photonic applications.

Thermal stress reduction for a Czochralski grown single crystal
In this paper an optimal control approach for thermal stress reduction inside a Czochralski grown single crystal is presented. Using the lateral heat flux as a control variable, an optimal control formulation for minimizing thermal stress with a given crystal shape is derived. Since thermal stress is also affected by the lateral shape of crystals during growth, the level of the stress can be re...

Design and Characterization of Photonic Crystal Fiber for Sensing Applications
A simple structure of Photonic Crystal Fiber (PCF) for gas sensing and chemical sensing has been proposed in this paper. Index guiding properties of proposed PCF have been numerically investigated by using finite element method (FEM). From the numerical result, it is shown that the relative sensitivity and confinement loss depend on geomatrical parameters and wavelength. The relative sensitivit...
