As new alternative optically stimulated luminescence (OSL) materials to Eu-doped CsBr and Tl-doped RbBr, we synthesized In-doped RbBr transparent ceramics by spark plasma sintering. All the ceramics had a transmittance of approximately 60% from 300 to 800 nm. In its photoluminescence (PL) and scintillation spectra, In-doped RbBr showed an emission peak at 500 nm due to 3P1→1S0 transitions of In+ ions. The PL and scintillation decay time constants were approximately 4.1 μs. OSL was observed upon optical stimulation at 700 nm. The 0.5% In-doped RbBr had a linear OSL response in the dose range from 0.3 mGy to 3 Gy.
