摘　　要：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 diffiaction data. Ab- sorption and fluorescence spectra were measured at room temperature. The fluorescence lifetime of KTb（WO4）2 was 114 μs. The specific heat of the KTh（WO4）2 crystal was also measured at room temperature.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.
