Lithium-indium oxide is one of the candidate materials as solid-state scintillators for solar neutrinos due to an inverse beta -decay of In-115 to Sn-115. On the other hand, when doped with rare-earth ions such as Eu3+ or Sm3+, it becomes a promising phosphor material. In this report we present a simple solid-state procedure for preparation of LiInO2:Eu3+ powders. X-ray diffraction confirmed product in tetragonal structural form (space group: I4(1)/amd) and no impurity phases were detected. Then, high resolution photoluminescence emission measurements were performed at room and low temperatures to find D-5(0) - GT F-7(J). Emission kinetics from D-5(0) level exhibited pure single exponential behavior with lifetime of about 1.5 ms. Maximum energy splitting of F-7(1) manifold is recorded as a function of temperature.
