| 摘 要： | Capsulating guest into the nanometer yoids of zeolites is a effective way to form novel host-guest material. In our work, stoichiometric SrAl2O4: Eu^2 , Dy^3 sol guest was prepared by sol-gel method and assembled into the nanometer channels of zeolite ZSM-5 host through mechanical mixing, hydrothermal reaction and microwave heating reaction, respectively. After being reduced and diffused in a microwave muffle, the fluorescence spectra of the host-guest materials exhibit remarkable blue shifts in comparison of that of SrAl2O4 : Eu^2 , Dy^3 . Some interesting phenomena in the assembled hostguest materials are that the after-glow emission spectra exist two bands at about 400 nm and 517 nm and the relative strengths of these two bands can be adjusted by changing the assembly methods and the assembly concentration. These are attributed to the fact that the phosphor was capsulated into the voids of zeolite ZSM-5 and generated the quantum size effect and the host-guest effect.

| Abstract: | Capsulating guest into the nanometer yoids of zeoites is a effective way to form novel host-guest matreial.In our work,stoichiometric SrAl 2O 4:Eu 2 ,Dy 3 sol guest was prepared by sol-gel method and assembled into the nanometer channels of zeolite ZSM-5 host through mechanical mixing,hydrothermal reaction and microwave heating reaction,respectively.After being reduced and diffused in a microwave muffle,the fluorescence spectra of the host-guest materials exhibit remarkable blue shifts in comparison of that of SrAl 2O 4:Eu 2 ,Dy 3 . Some interesting phenomena in the assembled host-guest materials are that the after-glow emission spectra exist two bands at about 400 nm and 517nm and the relative strengths of these two bands can be adjusted by changing the assembly methods and the assembly concentration.These are attributed to the fact that the phosphor was capsulated into the voids of zeolite ZSM-5 and generated the quantum size effect and the host-guest effect. |
