Mechanoluminescence characterisation of γ-irradiated (KNa)Br:Ce3+ phosphor

► ML intensities are found to be dependent on concentrations of Ce3+ ion and γ-rays radiation dose. ► Variation of peak ML intensity of (KNa)Br:Ce(0.5 mol%) with different γ-rays dose is found as linear up to 2.5 kGy high dose. ► ML characterisation shows good linearity, less fading, simple ML glow curve structure and stability of compounds prepared material may be of use for radiation dosimetry.
