We fabricated Er2O3-doped gallate glasses and tellurite glasses for near-infrared emitting scintillators. Both the glasses showed efficient scintillation in a near-infrared wavelength range due to the electronic transition between 4f levels in Er3+ ions. The lowest detectable dose rate limit was 5 mGy/h for the Er2O3-doped gallate glasses and 0.5 mGy/h for the Er2O3-doped tellurite glasses.
