Elucidation of the structural features and photoluminescence properties of a hydrothermally-synthesized γ-KEu(MoO₄)₂ microcrystal phosphor with metastable orthorhombic structure and differences in the luminescence properties by structure transition due to Y³⁺-dilution

Abstract

Potassium europium molybdate, KEu(MoO4)2,is an intriguing material known for its efficient luminescence properties attributed to Eu3+ ions and its polymorphic nature. Despite its significance, research on the metastable γ-phase has...
