The scintillation properties of RbCa1-xEuxCl3 (x = 0.005, 0.03, 0.05, 0.08) single crystals grown from the charge obtained by the solution routine using the Bridgman-Stockbarger method are reported. The luminescence spectra of RbCa1-xEuxCl3 crystals show a single band with a maximum which position shifts from 437 to 443 nm with increase of mole fraction of Eu2+ from 0.005 to 0.08. The decay of the scintillation pulse can be described using single component and the decay time rises towards concentration of Eu2+ in crystals. The relative light yield achieves 55 per cent vs. NaI:Tl for RbCa0.92Eu0.08Cl3 sample.
