摘　　要：采用一步水热法,通过In^(3+)的掺杂,获得了尺寸可控的近红外(NIR)发光ZGO∶1.5%Cr,xIn(Zn_(1.4)Ga_(1.97-2x)O_(4)∶1.5%Cr,xIn,x=0%、0.1%、0.2%、0.3%、0.4%、0.5%)长余辉纳米颗粒(PLNPs),考察了In^(3+)掺杂量对ZGO∶1.5%Cr,xIn PLNPs尺寸大小、余辉发光性能以及晶体结构的影响。In^(3+)的掺杂不仅能有效控制ZGO∶1.5%Cr,xIn PLNPs尺寸,还可以增强发光和余辉时间。结果表明,当In^(3+)掺杂量为0.2%时,ZGO∶1.5%Cr,0.2%In PLNPs平均粒径为13.79 nm,分布最为均匀,粒径最小,NIR发光最强,余辉时间超过5 d,可通过LED灯再激发。In^(3+)的掺杂对ZGO∶1.5%Cr,xIn PLNPs的晶体结构无影响,均为纯相的尖晶石结构。Size controllable near infrared-emitting ZGO∶1.5%Cr,xIn(Zn_(1.4)Ga_(1.97-2x)O_(4)∶1.5%Cr,xIn,x=0%,0.1%,0.2%,0.3%,0.4%,0.5%)persistent luminescent nanoparticles(PLNPs)were prepared via a facile one-step hydrothermal method.The size and persistent luminescence properties of ZGO∶1.5%Cr,xIn PLNPs depended on codoping amounts of In^(3+).The results showed that when the doping amount of In^(3+)was 0.2%,the average particle size of ZGO∶1.5%Cr,xIn PLNPs was the smallest(13.79 nm),and the NIR luminescence was the strongest.The afterglow time was estimated for 5 d,and can be re-excited by LED lamp.ZGO∶1.5%Cr,xIn PLNPs were pure spinel structure,and the doping of In^(3+)did not affect the crystal structure of PLNPs.
