Dy 3+ Activated Nearly White Emitting NaCdPO 4 as Potential Phosphors for Solid State Light Applications

摘要: A series of phosphate based phosphors NaCd 1− x PO 4: x Dy 3+(x= 0.02–0.1) are prepared by adopting conventional solid state reaction routes. The prepared phosphors are well characterized by x-ray diffraction to establish the phase purity while a field emission scanning electron microscope is used to detect the microstructure. The surface chemical composition, an important aspect of this work, is established by x-ray photoelectron spectroscopy. The photoluminescence excitation spectra are recorded at room temperature …
