The influence of Eu content on scintillation properties of single crystals of K(Sr1-xEux)2Cl5 composition has been studied. The single crystals were grown using the directional crystallization (Bridgman method). The dependence of the scintillation parameters (light yield, energy resolution) of K(Sr1-xEux)2Cl5 single crystals on the Eu content reaches the optimum at x = 0.01. The absolute light yield of the K(Sr0.99Eu0.01)2Cl5 single crystal was estimated as 38000 photons per MeV.
