“…Oxide-based phosphors were widely utilized in various optoelectronic and displaying devices due to their high thermal stability, chemical stability and excellent optical properties [1][2][3][4]. An unusual blue phosphor Sr 2 CeO 4 was first prepared using the combinatorial techniques by Danielson et al in 1998 [5].…”

“…The emission spectrum is dominated by 5 D 0 → 7 F 2 hypersensitive transition (Δ J02), which is because the Eu 3+ is located at a low symmetry local site in the M 2 V 2 O 7 (M 0 Sr, Ba) host lattice. Moreover, the splitting number of 5 D 0 → 7 F j transitions can provide information of the surroundings of the Eu 3+ ions [26,27], and the site symmetry of Eu 3+ ion with a maximum number of lines "2J+1" for each lattice site. Unique 5 D 0 → 7 F 0 (588 nm) transition indicates that the Eu 3+ ions occupy single sites in both Sr 2 V 2 O 7 and Sr 2 V 2 O 7 lattices.…”

A solution combustion route for the synthesis of Eu(3+)-activated M(2)V(2)O(7) (M = Sr, Ba) and their luminescent properties have been investigated. Structure and luminescent characteristics of Sr(2)V(2)O(7):Eu(3+) and Ba(2)V(2)O(7):Eu(3+) nanophosphors have been studied by x-ray diffraction, scanning electron microscopy, transmission electron microscopy, fluorescence spectrometry and Fourier transform infra-red spectroscopy. The incorporation of Eu(3+) activator in these nanoparticles has been checked by luminescence characteristics. These nanoparticles have displayed red color under a UV source which is due to characteristics transition of Eu(3+) from (5)D(0) → (7)F(2) at 613 nm in both Sr(2)V(2)O(7):Eu(3+) and Ba(2)V(2)O(7):Eu(3+) nanophosphors. In addition, the optimal Eu(3+) - doped contents of Sr(2(1-x))Eu(2x)V(2)O(7) and Ba(2(1-x))Eu(2x)V(2)O(7) nanophosphors for both were 4 mol%.

“…[13][14][15][16][17][18][19][20][21] A more complete understanding of the optical properties for perovskite-based materials is a prerequisite to eventual technological application, which is a key role for defects/ impurities and other structural order-disorder effects. 7,22 Numerous efforts have been expended to understand the mechanism for optical emissions, particularly photoluminescence (PL) effects [23][24][25][26][27][28][29][30] where device performance is strongly influenced by the energy and lifetime of the excited states. Borja-Urby et al reported the photocatalytic activity for pure BZO and BZO bismuth doped.…”

First-principles calculations set the comprehension over performance of novel cathodoluminescence (CL) properties of BaZrO 3 prepared through microwave-assisted hydrothermal. Ground (singlet, s*) and excited (singlet s** and triplet t**) electronic states were built from zirconium displacement of 0.2 Å in {001} direction. Each ground and excited states were characterized by the correlation of their corresponding geometry with electronic structures and Raman vibrational frequencies which were also identified experimentally. A kind of optical polarization switching was identified by the redistribution of 4d z 2 and 4d xz (Zr) orbitals and 2p z O orbital. As a consequence, asymmetric bending and stretching modes theoretically obtained reveal a direct dependence with their polyhedral intracluster and/or extracluster ZrO 6 distortions with electronic structure. Then, CL of the as-synthesized BaZrO 3 can be interpreted as a result of stable triplet excited states, which are able to trap electrons, delaying the emission process due to spin multiplicity changes.
