Luminescence in undoped CaYAl3O7 produced via the Pechini method

Physica B: Condensed Matter, 2017
Abstract The luminescent properties of CaYAl3O7 (CYAM) were carried out in undoped powder samples produced via Pechini method. The thermal analysis combined with XRD measurements showed that 1000 °C/4 h is the best condition for the CYAM synthesis. Morphological analysis showed submicrometric particles with irregular shape.
