We report the luminescence and the scintillation properties of a newly developed thallium magnesium chloride (TlMgCl3) crystal. The crystal sample can be easily fabricated from the melt using the Bridgman method. The photoluminescence band appeared near the wavelength of 405nm under excitation at 230nm. An X-ray-induced scintillation spectrum showed an intense emission band near the wavelength of 405nm. The decay time constant was estimated to be approximately 60 ns (>25%) and 350 ns (>75%) using a bi-exponential fitting. The scintillation light yield reached 46,000 photons/MeV with an energy resolution of 5% at 662 keV.
