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.
