New findings for Ba₂YCl₇ activated with 4f transition elements Eu²⁺ and Ce³⁺ are presented. These phosphors were synthesized using wet chemical procedure. As-synthesized Ce³⁺-doped sample exhibited intense photoluminescence (PL). For Eu²⁺ activation, further heat treatment in reducing atmosphere at 700^oC was necessary. Intense emission from these activators could be identified with the allowed intra-configurational transitions. Ease of preparation combined with intense PL make these hitherto unexplored phosphors potential candidates for applications such as scintillation. Keywords: halide, photoluminescence, phosphor.
