The blue cathodoluminescence (CL) characteristics at room temperature were reported for thin films of barium chloride hydrate doped with cerium. The CL spectrum consisted of two peaks at 443 and 485 nm due to 4f-5d transitions of cerium ion. It was shown that barium chloride hydrate doped with cerium is a blue phosphor that exhibits relatively efficient luminescence after processing at low temperatures.
