Luminescence Characteristics

Sr3SiO5:Eu2+ nanophosphors for white LEDs were synthesized by solgel method. The crystalline phases were examined with X-ray diffraction (XRD). Luminescence properties were studied, and effects of the Sr/Si ratio on the emission spectra were also studied. The nanophosphor showed a broad excitation band from 300 to 500 nm and a broad band emission peaking at 593 nm due to the typical electron transition of Eu2+ 4f74f65d1. Remarkable enhancement in luminescence characteristics was observed when excesses silica was used. This phenomenon may be attributed to the improvement of Si sensitized the luminescence of Eu2+ in the Sr3SiO5 nanophosphor.

AbstractIn this work, strongly blue emitting Ce3+-activated BaAl2O4 nanophosphors were successfully synthesized by a sol–gel technique. The crystal structure, morphology, and microstructure of the nanophosphors have been studied by X-ray powder diffraction, field emission scanning electron microscopy, and high-resolution transmission electron microscopy. The photoluminescence spectra show the impact of concentration variation of Ce3+ on the photoluminescence emission of the phosphor. These nanophosphors display intense blue emission peaking at 422 nm generated by the Ce3+ 5d → 4f transition under 350 nm excitation. Our results reveal that this nanophosphor has the capability to take part in the emergent domain of solid-state lighting and field-emission display devices.
