A highly efficient and stable green-emitting mesoporous silica (MP)–(Cs 0.4 Rb 0.6 )PbBr 3 perovskite composite for application in optoelectronic devices

We have, for the first time, reported a highly efficient MP–(Cs 0.4 Rb 0.6 )PbBr 3 luminescent material for application in optoelectronic devices. MP–(Cs 0.4 Rb 0.6 )PbBr 3 with red-emitting Sr 2 Si 5 N 8 :Eu 2+ phosphor is applied to an InGaN blue chip and compared with green-emitting (Cs 0.4 Rb 0....

Summary:We have, for the first time, reported a highly efficient MP–(Cs 0.4 Rb 0.6 )PbBr 3 luminescent material for application in optoelectronic devices. MP–(Cs 0.4 Rb 0.6 )PbBr 3 with red-emitting Sr 2 Si 5 N 8 :Eu 2+ phosphor is applied to an InGaN blue chip and compared with green-emitting (Cs 0.4 Rb 0.6 )PbBr 3 perovskite nanocrystals (NCs). MP–(Cs 0.4 Rb 0.6 )PbBr 3 achieves a conversion efficiency of 80.9 lm W −1 under a forward-bias current of 150 mA. We propose MP–(Cs 0.4 Rb 0.6 )PbBr 3 as a promising green-emitting material that can replace the conventional inorganic phosphor.
