but changed the luminescence intensities.When the doping concentration of B3+ is x=0.05

the luminescence intensity is the strongest.Furthermore

B3+ doping also improved the LLP properties.The optimized LLP performance could be obtained when the doping concentration of B

is x=0.10 with the LLP decay curves.It was due to more traps caused by the unequal doping of B
