Undoped and 0.1% Tb-doped KHSi2O5 single crystals were synthesized by the hydrothermal method, and their scintillation and dosimetric properties were systematically investigated. The scintillation spectra of the Tb-doped KHSi2O5 single crystal exhibited an emission peak at 330 nm originating from the host material and additional peaks in the 490–620 nm range, corresponding to the 4f–4f transitions of Tb3+ ions. The thermally stimulated luminescence (TSL) glow curves showed two peaks at approximately 80 and 300 °C for all the Tb-doped samples. In the TSL dose response of the Tb-doped sample, the lowest detectable dose was 30 mGy, and a linear dose response was observed over the dose range of 30–3000 mGy.
