Abstract

We synthesized a violet-blue phosphor Ba 2 Al B 4 O 9 Cl : Eu 2 + with a solid-state reaction. The excitation and emission spectra of this phosphor showed that all were broadband due to 4 f 7 4 f 6 d 1 transitions of Eu 2 + . The phosphors with different Eu 2 + concentrations presented violet-blue luminescence for ultraviolet [(UV) 250 390 nm ] excitation. The optimum concentration of Eu 2 + in Ba 2 Al B 4 O 9 Cl : Eu 2 + is determined to be 6 mol . % . The luminous efficiency was found to be 8.1 lm / W for the violet-blue fluorescent lamp and 3.2 lm / W for the violet-blue phosphor-converted light-emitting diode, respectively. Ba 2 Al B 4 O 9 Cl : Eu 2 + would be a promising phosphor for converting the UV radiation to violet-blue emission for a novel high light-conversion efficiency phototherapy illuminator.
