Abstract
The crystal structure of CaGa<sub>2</sub>O<sub>4</sub> can be described as [GaO<sub>4</sub>] tetrahedrons connecting with each other, forming large tunnels at the center, which are filled by Ca<sup>2+</sup>. Doping with Pr<sup>3+</sup> achieves yellow long persistent luminescence and mechanoluminescence.
