Read out test of inorganic-organic hybrid scintillator; Pr:LuAG single crystal covered with plastic scintillator are demonstrated. The Pr:LuAG sample coated with bis-MSB+TB-PVD containing WLS showed the better light output and energy resolution than the Pr:LuAG itself. Light output was increased up to 55% and energy resolution was also improved to 6.1%@662keV using APD (Hamamats S8664-8220). In the case of MPPC (Hamamatsu S10362_33_050 3600pixel-type), light output was increased up to 35% and energy resolution was also improved to 8.8%@662keV. Decay curve of the Pr:LuAG sample coupled with the WLS was also measured and successfully modeled.
