Photoluminescence and energy transfer in Tb3+-doped CeO2–Mn3O4 phosphor prepared by co-precipitation method

Terbium-doped CeO 2 –Mn 3 O 4 (CMO-Tb) phosphor was synthesized using co-precipitation and calcined at 500 °C. The material was characterized by X-ray diffraction (XRD), diffuse reflectance (DR), and photoluminescence (PL) spectroscopies. XRD analysis revealed that the main peaks...
