Abstract: Two laser crystals of Er3+:KLu(WO4)2 and Er3+/Pr3+:KLu(WO4)2 were successfully grown using the top-seeded solution growth technique with K2W2O7 as flux. Segregation coefficients of Er3+ ions in Er3+:KLu(WO4)2 and Er3+/Pr3+:KLu(WO4)2 crystals were 0.664 and 0.9, respectively.… read more here.

Abstract: Abstract It is highly significant to develop multi-mode optical anti-counterfeiting materials to efficiently fight against counterfeit products. In this study, we chose ferroelectric K0.5Na0.5NbO3 (KNN) with excellent photochromism properties as the host and rare-earth Er3+… read more here.

DOI: 10.1016/j.jnoncrysol.2020.120511
Abstract: Abstract Nd3+-Er3+-Pr3+ tri-doped tellurite glasses with lower phonon energy (768 cm−1) were prepared by conventional melt-quenching method. Under the excitation of 488nm, an ultra-broadband emission from 760 to 1150 nm with full-width at half-maximum (FWHM)… read more here.
