Summary:•HfO2 nanocrystals were successfully synthesized by precipitation method.•The crystallite size of 23.6 ± 2.7 nm (mean ± σ) according to Scherrer equation.•Emission Spectra showed a broad emission band between 350 and 550 nm and a peak at 341 nm.•TL growth curve showed exponential dose response to beta irradiation (2–50 Gy).•OSL growth curve presented linear dose response to beta irradiation (2–50 Gy).
