Effects of synthesis, doping methods and metal content on thermoluminescence glow curves of lithium tetraborate

Lithium tetraborate: Li(2)B(4)O(7), (LTB) has been synthesized and doped with various Mn content by different methods, such as, high temperature solid state synthesis and solution assisted synthesis methods. Powder XRD results proved the formation of solid-solution by replacing Mn with Li ions in LTB lattice at lower amount of Mn doping, for example 0.1-3.0% Mn doping. In this research TL glow curves of Mn doped lithium tetraborate (LTB: Mn) produced by using different synthesis and doping methods and the effects of Ag, P and Mg as co-dopant were investigated. Structural and morphological analyses of products were done by using Fourier Transform Infrared spectroscopy (FTIR), Powder X-Ray Diffraction (XRD), Scanning Electron Microscopy (SEM), Transmission Electron Microscopy (TEM) and Raman Spectroscopy.
