A new Ag-doped crystalline SiO2 based OSL phosphor is developed. This phosphor shows good OSL properties and the sensitivity is comparable to that of the commercial Al2O3:C. For the luminescence integrated over initial 3s, BSL (blue stimulated luminescence) and GSL (green stimulated luminescence) sensitivities were found to be 0.54 and 3.1 times the respective BSL and GSL sensitivities of the commercial Al2O3:C. The PL emission is found to vary from UV to visible range with the change in the Ag concentration. Thus the material can be used as BSL or GSL phosphor. The simple preparation procedure, fast decay, very good sensitivity will make this phosphor suitable for real-time dosimetric applications, using OSL technique.
