Sr[sub 2]B[sub 2]P[sub 2]O[sub 10]:Eu[sup 2+],Mn[sup 2+],Ba[sup 2+]: A Potential Single-Phase White Light-Emitting Phosphor for UV Light Emitting Diodes

White light emission is generated by combining the blue and red emissions of and , respectively, and by adding the co-doping element in a single host lattice of . The effect of concentration on the emission intensity of is studied, and the emission intensity reaches a maximum at 1% . Energy migration over sites occurs, resulting in concentration quenching, and the concentration quenching mechanism is d-d interaction by Dexter theory. exhibits a high absorption in the near-UV region, and energy transfer from to occurs in . When is introduced in , a green emission band appears and white light is obtained. The results indicate that is an efficient "single host lattice phosphor" for solid-state lighting technology using a UV light emitting diode to generate white light.
