摘要
An effect of variation of slit widths of excitation and emission monochromators on emission intensity, peak position and asymmetric ratio of Eu3+ has been observed in YPO4:Eu3+. Stark splitting is observed. Eu3+ ion occupies D2d site symmetry in crystal lattice. However, asymmetric ratio is observed to be lesser in value ∼≤1.5. The possible explanation for low value of asymmetric ratio is explained.
