The growth of a Mn-doped LiAlO<sub>2</sub> single crystal by the Czochralski (CZ) method and the characterization of its spectroscopy and thermoluminescence (TL) are presented. The X-ray rocking curve and chemical etching analysis show that the as-grown crystal has good crystallinity. The full-width at half-maximum (FWHM) of the LiAlO<sub>2</sub> (200) \omega rocking curve is 23.2 arcsec and the etching pits density of the (100) plane is (1.6–4.0)×10<sup>4</sup> cm<sup>-2</sup>.
