摘要

通过对ZnS:Mn

不同含量的钠硼硅玻璃发光和激发光谱测量

发现Mn离子可能占据替位(Mn

)Sub和间隙(Mn

)int两种格位.进一步的电子顺磁共振(Electron Paramagnetic Resonance

EPR)实验证实了这一判断

并从EPR谱确认(Mn

)Sub

(Mn

)

int

和Mn团三种格位态的存在.观测到g因子和超精细结构(HFS)常数随纳米晶粒径的减小而增大.这可能是由于量子限域效应下ZnS的sp

和Mn的3d

电子态杂化和表面态所引起的.

Abstract

It was found that Mn

may occupy(Mn

)

sub

and(Mn

)--int-sites by luminescence and excitation spectra.EPR measurements support this conclusion.(Mn

)

sub

(Mn

)

int

and nclusters were identified.The

factor and HFS constants increases with decreasing the diameters of the nanocrystals.It might be due to the hybridization between sp and d states by quantum confinement effects and the surface states.
