| 中文摘要: |
| 通过水热法合成不同铟（In）离子掺杂的ZnGa1.99-xInxO4:Cr3+0.01（x=0，0.1，0.2，0.3，0.4）长余辉纳米粒子（PLNPs）。在最佳In离子掺杂浓度下，通过改变制备时加入浓氨水的量来调节的pH，当pH为10时，得到了余辉时长可持续96小时的PLNPs（ZnGa1.89In0.1O4:Cr3+0.01）。In离子掺杂浓度x =0.1时，PLNPs的晶体结构保持不变，粉末粒径在15.36 nm，标准差为4.07 nm，余辉强度和时间都大于In未掺杂的ZnGa1.99O4:Cr3+0.01。基于ZnGa1.89In0.1O4:Cr3+0.01优良的发光性能，探究了在0.005-20 μM的多巴胺浓度下PLNPs发光强度的变化，随着多巴胺浓度的增加，发光信号会减弱，且呈良好的线性关系，相关系数R平方为0.998，ZnGa1.89In0.1O4:Cr3+0.01可用于高灵敏检测多巴胺。 |

| ZnGa1.99-xInxO4:Cr3+0.01 (x=0,0.1,0.2,0.3,0.4) persistent luminescence nanoparticles doped with different content of In were synthesized by hydrothermal method. ZnGa1.89In0.1O4:Cr3+0.01 with afterglow lasting for 96 hours at pH 10 was obtained by varying the ammonia volume during preparation at the optimal In doping. After doping of In, the crystal structure of ZnGa1.89In0.1O4:Cr3+0.01 with a small size of 15.36 nm with a standard deviation of 4.07 nm was unchanged. The persistent luminescence intensity and persistent luminescence time were higher than the without In doping ZnGa1.99O4:Cr3+0.01. Based on the excellent luminescence performance of ZnGa1.89In0.1O4:Cr3+0.01, the changes of persistent luminescence intensity of persistent luminescence nanoparticles at different dopamine concentrations were investigated, and the persistent luminescence intensity decreased with increasing dopamine concentration in a good linear relationship with a correlation coefficient R squared of 0.998. ZnGa1.89In0.1O4:Cr3+0.01 can be used as a highly sensitive dopamine sensor and an excellent nanoprobe for in vivo imaging. |
