| 摘 要： | 采用微乳液的方法制备了平均粒径为85 nm的ZnS纳米粉体。主要测试了咔唑衍生物及8-羟基喹啉与ZnS纳米粒子复合后在四氢呋喃、N,N-二甲基甲酰胺中的单/双光子荧光特性。研究发现咔唑衍生物的双光子荧光强度较未加入纳米ZnS时只有提高不足20%,而8-羟基喹啉与纳米ZnS复合后得到了一种新的发光体系,其荧光强度可提高2~4倍,同时荧光发射峰出现了较大程度的红移,其红移达116 nm。

| Abstract: | The average size of 85 nm ZnS nanoparticles was prepared by microemulusion.The one/two-photon fluorescence properties of ZnS nanocomposite with carbazole derivatives and 8-hydroxyquinoline in tetrahydrofuran and N,N-dimethylformamide solution were measured.The results show that the two-photon fluorescence intensity enhanced less than 20% when the carbazole derivatives were coated by ZnS nannoparticles,but a new luminescence was obtained by 8-hydroxyquinoline nanocomposite ZnS with the enhancement of 2~4 fold fluorescence intensity and 116 nm red-shift. |
