# Spectroscopic studies and crystal field calculation for Nd$^{3+}$ in single crystal K$_2$YF$_5$

Abstract : Optical properties of Nd3+ doped into K2YF5 single crystal have been analysed. A detailed electronic energy level scheme of Nd3+ ion in the crystalline structure has been deduced from the absorption, emission and time resolved spectra recorded at 12 K. Energy level simulation of Nd3+ ions in K2YF5 has been carried out and the phenomenological crystal field parameters were determined. The root mean square (r.m.s.) standard deviation is 19.0 cm(-1), indicating a satisfying agreement between the calculated and experimental levels. The results are also compared to those reported for BaY2F8:Nd3+ and LiYF4:Nd3+ crystals, and the tendency of a covalence and crystal field decreasing effect was observed from K2YF5, BaY2F8 to LiYF4.
