摘要

This paper reports the growth and spectral properties of Cr3+:Na2Mg5(MoO4)(6) crystals. The Na2Mg5(MoO4)(6) crystal was grown from a flux of Na2MO2O7 by the top seeded solution growth method. The absorption cross-sections are 0.692 x 10(-19) cm(2) at 507 nm and 1.151 x 10(-19) cm(2) at 736 nm, respectively. The emission cross-section is 1.62 x 10(-19) cm(2) at 914 nm with FWHM of 192 nm. Based on the absorption and emission spectra, the crystal field strength Dq, the Racah parameters B and C, effective phonon energy h omega and the Huang-Rhys factor S were calculated. The spectral properties of Cr3+: Na2Mg5(MoO4)(6) crystal demonstrate a good potential for tunable laser material. (C) 2015 Elsevier B.V. All rights reserved.
