Description	Non-stoichiometric strontium hafnate powder samples were prepared by reaction in solid state using the startintg SrO-HfO2 mixture with different rations of binary constituents. XRD analysis was systematically performed and correlated with the observed radioluminescence characteristics. In the sample with starting surplus of HfO2 a a Sr0.98Hf1.02O3.02 phase was identified which is associated with the 334 nm emission band. Its radiluminescence intensity exceeds more than thirty times that of bismuth germanate (BGO) standard single crystal scintillator. In the sample with initial surplus of SrO, two different Sr-rich phases were identified in the sintered material. Their radioluminesce spectra peak within 420-430 nm and intensities are comparable to that of BGO.
