文摘
- •
We present VUV emission and excitation spectra of NaMgF3:Yb2+.
- •
Formation of free excitons leads to emission from intrinsic and extrinsic excitons.
- •
We deconvolute the emission to separate the two overlapping exciton bands.
- •
The excitation spectra show two mechanisms for forming impurity-trapped excitons.
