Abstract
(Mg<sub>1−x</sub>Mn<sub>x</sub>)<sub>2</sub>Al<sub>4</sub>Si<sub>5</sub>O<sub>18</sub>(<italic>x</italic>= 0–1.0) cordierite shows structural changes from β-phase (<italic>x</italic>= 0–0.2) to α-phase (<italic>x</italic>= 0.3–0.9) and Mn-cordierite (<italic>x</italic>= 0.95–1.0) (β-phase). Luminescence characteristics of Mn<sup>2+</sup>can clearly identify phase and site-occupation.
