The halophosphate phosphor includes a halophosphate including an alkaline earth metal including at least calcium; europium; and a halogen including at least chlorine. An elution amount of chlorine ions after the halophosphate phosphor is brought into contact with 10 times by mass of pure water at 85° C. for five hours is 7 ppm or less.

The present invention relates to highly polarizable 3D organic perovskites of the general formula ABX.sub.3, prepared by introducing halogen functional groups in the A-site cation (in which the A and B sites are occupied by organic cations and the X site is a monovalent non-metallic counterion). The (DCl)(NH.sub.4)(BF.sub.4).sub.3 crystal exhibits a strong linear electrooptic (EO) effect with an effective EO coefficient of 20 pmV.sup.−1, which is 10 times higher than that of metal halide perovskites. These 3D organic perovskites are solution processed and compatible with silicon, and illustrate the potential of rationally-designed all-organic perovskites for use in on-chip modulators, electro-optic devices, piezoelectric devices, or silicon photonics devices.
