| description | Abstract This study reports the synthesis and characterization of Na2Ca4(PO4)3F phosphor doped with Dy3+, Tb3+, and Eu3+ ions were synthesized using a conventional solid-state method. The phase formation was confirmed by X-ray diffraction (XRD). Functional group analysis through Fourier transforms infrared spectroscopy (FTIR) and morphological evaluation via scanning electron microscope (SEM) and EDS revealed good crystallinity and elemental distribution. The triple-doped phosphor exhibited color-tunable emissions under near-UV excitation, covering the blue, green, yellow, and red regions, resulting in efficient white light output. Photoluminescence (PL) studies indicated effective energy transfer among the dopant ions. Additionally, the phosphor was applied as a down-conversion layer on silicon solar cells using the doctor blade technique. The coated cells showed a 16.33% improvement in efficiency compared to uncoated cells. The combined optical and photovoltaic performance highlights the potential of Na2Ca4(PO4)3F: Dy3+/Tb3+/Eu3+ as a multifunctional material for white light-emitting diodes and solar energy devices. |
