Abstract
Ca<sub>8</sub>Mg<sub>3</sub>Al<sub>2</sub>Si<sub>7</sub>O<sub>28</sub>:Ce<sup>3+</sup>,Eu<sup>2+</sup> phosphors with a melilite structure are designed and prepared for applications in optical thermometry. Their emission colours are tunable due to the energy transfer and thermal quenching of Ce<sup>3+</sup> and Eu<sup>2+</sup>.
