A Strontium Aluminosilicate SrAl2SiO6 Offering a Scalable Route to Persistent Luminescent Materials

The substitution of silicon into SrAl2O4 is of interest for the development of new persistent luminescence phosphors with complementary excitation and emission wavelengths, especially in the form of transparent ceramics or glass-ceramics by the glass-crystallization approach. Application of this approach to the series Sr1-x/2Al2-xSixO4 (0 <= x <= 1) has previously produced two different solid…
