The present paper reports synthesis and thermoluminescence studies of bulk CdS. The absorption spectra are observed and reported. The band gap energy of the bulk CdS corresponding to the absorption edge of pure CdS was 2.61 eV. We calculated kinetic parameters such as activation energy (E), order of kinetics (b), and frequency factor (s) with trap parameter. We found that shape factor μ in the range of 0.27–0.32 showed first-order kinetics. The value of the activation energy was 1.55–2.17 eV and the frequency factor 1.49 × 1015–6.6 × 1020 s−1.
