Growth, structural, thermal properties and spectroscopic characteristics of KTb(WO4)2 single crystal

KTb(WO4)2(KTW) single crystal with dimensions up to 30 mm×30 mm×10 mm was grown by the top-seeded solution growth (TSSG) method for the first time. The crystal structure was refined at room temperature by using single crystal X-ray diffraction data. Absorption and fluorescence spectra were measured at room temperature. The fluorescence lifetime of KTb(WO4)2 was 114 μs. The specific heat of the KTb(WO4)2 crystal was also measured at room temperature.
