A self-designed traveling zone melting method was employed to fabricate perovskite CsPbBr3 crystals, which is helpful for impurities removing and moisture excluding. A large-size CsPbBr3 crystal with a dimension of ϕ 25 mm× 60 mm is successfully obtained. The as-grown crystal shows orange color and displays an excellent transmittance of 78.6% in the range of 600 nm - 2000 nm wavelength. It is revealed by DSC analysis that there is phase transition at 88.1℃ and 131.25℃, respectively. The band gap Eg of the crystal is calculated to be 2.25 eV. The above results prove that the traveling zone melting method is indeed a potential approach for large size and high quality CsPbBr3 crystal preparation.

Key words: traveling zone melting method, CsPbBr3 crystal, transmittance, band gap
