Figure 6

(a) The lifetime decay curves for the Eu(1) in SPBO_Cl:0.04Eu2+ phosphors (x = 0, 0.1, 0.3, and 0.5) excited at 365 nm and monitored at 446 nm. The inset shows the calculated energy transfer efficiency (ηET) from Eu(1) to Eu(2) with a varying B3+ doping content. (b) The lifetime decay curves for Eu2+ in the SPBO_Cl:0.04Eu2+ (x = 0.1) phosphor excited at 275 nm and monitored at 448 and 564 nm. The lifetime decay curves were fitted using the double-exponential equation I(t) = I0 + A1exp(−t/τ1) + A2exp(−t/τ2).
