Enhanced photoluminescence of a CsPbBr3/Al2O3 film heterojunction enabled by coupling of gold nanoparticles
We studied an enhanced photoluminescence (PL) effect of CsPbBr _3 /Al _2 O _3 heterojunction by using gold nanoparticls (NPs). The CsPbBr _3 /Al _2 O _3 heterojunction and CsPbBr _3 /Au/Al _2 O _3 heterojunction were respectively prepared on porous Al _2 O _3 film by using a colloidal self-assembly...
