Photoluminescence in a Novel Aldo-Keto Synthesized YPO₄:Eu³⁺ Nanophosphor

Abstract:

In this report, Aldo-keto (Aldehydes and Ketones) method, a soft root of synthesis of inorganic materials was employed to prepare YPO4:Eu³⁺ nanophosphors. The as-prepared samples were characterized by X-ray diffraction (XRD), and scanning electron microscope (SEM) for structural and morphological studies. The complete agreement of XRD with standard ICDD data confirms the formation of required phase. The particle size conformation was done through Debye Scherrer formula. The luminescence studies were carried out by photoluminescence (PL) spectroscopy. The PL spectra reveal that the orange emission (⁵D₀→⁷F₁) was more intense than a normal red emission (⁵D₀→⁷F₂). Also the tuning of color purity was done through concentration variation.
