Abstract

A rare earth oxyborate crystal K₂Nd₂O(BO₃)₂ has been grown by means of high temperature solution method for the first time. It crystallizes in monoclinic P2₁/c (No. 14) space group, and the lattice parameters are a=11.318(6) Å, b=6.575(4) Å, c=10.689(6) Å, β=117.062(12)°, and Z=4. The absorption spectrum, emission spectrum, and fluorescence lifetime of K₂Nd₂O(BO₃)₂ have been evaluated, and the foundational spectral parameters have been analysed according to the Judd-Ofelt theory. The high concentration of activated ions (1.13×10²² ions/cm³), large absorption coefficient (87.63 cm⁻¹), long fluorescence lifetime (91.2 μs), and large emission cross section (2.03×10⁻²⁰ cm²) of K₂Nd₂O(BO₃)₂ suggest its potential applications of microchip lasers.
