“…This can be concluded that the strong absorption and high quantum efficiency of Eu 3+ for excitation in the ultraviolet region. As known to all, intensities of transitions between different J levels are dependent on symmetry of the local environment of Eu 3+ [14]. There are groups of lines between 580 nm and 705 nm in the emission spectrum (Fig.…”

Because fossil fuels are becoming scarce and because of the expected climate change, our standard of living can only be maintained by a significant increase in energy efficiency. Large amounts of energy are consumed for lighting and during operation of displays. Thus, the targets are the development of economical light sources like white-light-emitting diodes and display panels with enhanced efficiency. Solar energy is converted into electricity by solar cells, and their efficiency must be improved considerably. A possible contribution might be delivered by phosphors which allow the conversion of thermal radiation into electrical energy. Although the target of energy efficiency is very important, we must not overlook that medical imaging diagnostic methods require efficient and sensitive detectors. For the solution of these central questions, inorganic solid-state materials doped with rare-earth ions are very promising and are therefore in the focus of current research activities.

“…Thus for both type of applications efficient phosphors are required which show absorption in the range between 140 nm and 180 nm [1][2][3][4]. Phosphor for PDP and Hg-free fluorescent lamps requires high conversion efficiency and excellent color purity under the VUV radiation.…”

Tb doped AZr 2 (PO 4 ) 3 (AZP) green phosphors were synthesized by novel solution combustion method and the excitation spectra of pure compound in the vacuum ultraviolet (VUV) regions are investigated. The VUV characteristic was optimized by Tb 3+ concentration and by alkali metals A + (Li, Na, K) contents. The concentration quenching was observed when the concentration of Tb 3+ was 2.0 at % of Zr 2 . The band ranging from 130 to 160 nm in excitation spectra is due to the absorption band of host lattice or PO 4 groups; the band at 160-200 nm is related to the charge transfer (CT) transition of O-Zr. The strong band at 225 nm and the weak band at 261 nm in the excitation spectra are assumed to the spin-allowed and spin-forbidden f-d transitions (4f 8 → 4f 7 5d 1 ) of Tb 3+ .The excitation and emission spectra indicate that the phosphors can be effectively excited by 147 nm and 172 nm and demonstrated a satisfactory green light performance. The high luminescent intensity, excellent color purity and chemical stability of AZr 2 (PO 4 ) 3 :Tb 3+ make it an attractive green emitting phosphors for mercury free luminescent lamp and plasma display panel. The prepared phosphor sample was characterized using X-ray diffraction (XRD), scanning electron microscopy (SEM) and Vacuum ultraviolet spectra were studied.
