Thermally stimulated luminescence studies of undoped and doped CaB₄O₇ compounds

Thermoluminescence of undoped and doped CaB₄O₇ with activators such as Cu and Mn has been investigated. The polycrystalline samples of undoped and doped CaB₄O₇ are prepared by melting method. The formation of CaB₄O₇ compound is checked by X-ray diffraction study and the compound is found to have ort...
