The Cr 3+ :KAl(MoO 4 ) 2 single crystal was grown by top seeding solution growth method (TSSG). Based on the absorption and emission spectra, the crystal field strength Dq, the Racah parameters B and C, the effective phonon energy ℏω and the Huang–Rhys factor S were calculated: Dq=1494.8 cm −1 , B=585.5 cm −1 and C=3049 cm −1 , ħω=373...
(Ba 0.32 Sr 0.68 ) 5 Nb 4 O 15 crystal with sizes of Ø 17×35 mm was grown successfully by Czochralski technique method. The thermal anisotropy was discussed. The principal coefficients of thermal expansion along (100), (010), (001) directions were precisely measured to be 1.308×10 −5 , 1.288×10 −5 , 1.478×10 −5 K −1 , respectively...
