Growth and spectroscopic properties of Nd 3+-doped Sr 3Y 2 (BO 3) 4 crystal

Abstract

A new crystal of Nd 3+:Sr 3Y 2 (BO 3) 4 with a dimension of Φ 15×30 mm 3 was grown by the Czochralski method. The grown crystal was characterized using X-ray diffraction. The absorption and emission spectra of Nd 3+:Sr 3Y 2 (BO 3) 4 were investigated. The absorption transition at 807 nm has an FWHM of 16 nm. The absorption and emission cross sections are 6.32×10 −20 cm 2 at 807 nm and 1.07×10 −19 cm 2 at 1065 nm, respectively. The luminescence lifetime τ f is 51.7 μs at room temperature.
