“…In our previous work, vdW–Ld forces were investigated in a range of materials . There is interest in the interband optical properties of and vdW–Ld forces in AlPO 4 due to its structural and optical similarity to SiO 2 , its application in battery and LED cathodes, as a mesoporous glass for molecular sieves and laser dyes, and because of the important role the phosphate complex ion plays in biological materials …”

The optical properties and electronic structure of AlPO4, SiO2, Type I collagen, and DNA were examined to gain insight into the van der Waals-London dispersion behavior of these materials. Interband optical properties of AlPO4 and SiO2 were derived from vacuum ultraviolet spectroscopy and spectroscopic ellipsometry, and showed a strong dependence on the crystals' constituent tetrahedral units, with strong implications for the role of phosphate groups in biological materials. The UV-Vis decadic molar absorption of four DNA oligonucleotides was measured, and showed a strong dependence on composition and stacking sequence. A film of Type I collagen was studied using spectroscopic ellipsometry, and showed a characteristic shoulder in the fundamental absorption edge at 6.05 eV. Ab initio calculations based on density functional theory corroborated the experimental results and provided further insights into the electronic structures, interband transitions and vdW-Ld interaction potentials for these materials.

“…Solid state NMR data have shown that the structure of AlPO 4 mesoporous glass is based on alternating AlO 4 and PO 4 tetrahedra. The chemical activity of AlO 4 and PO 4 is beneficial to tailor the luminescence of optical active species in the mesostructure [6,18,19]. In this case, the AlPO 4 mesoporous glass is an ideal host for incorporating rare earth to become active materials suitable for optical, electronic and sensing devices.…”

“…We already reported a simple aqueous sol–gel route yielding transparent and colorless stoichiometric AlPO 4 monolith glass. In contrast to silicate materials, it possesses mesoporous structure and more chemical activity to benefit the solidification of dopant. − Furthermore, AlPO 4 provides a suitable reductive atmosphere in the mesoporous network that dominates the stabilization of Eu 2+ ions. Hereby, it emerges as a promising host for tunable light emission of Eu ions.…”

Controllable simultaneous luminescent monolithic mesoporous AlPO 4 glasses doped with Eu ions were fabricated by dipping into a Eu-containing solution, followed by sintering in air. Reduction of partial Eu 3+ ions to Eu 2+ were achieved after annealing Eu 3+ ions in AlPO 4 meso-structure, which resulted in simultaneous luminescence of Eu 3+ (590 and 613 nm) and Eu 2+ (450 nm). Controllable luminescence and color tunability from blue to red were liable to obtain, which were characterized by emission spectra and described by CIE diagram. A deliberate tailoring of luminescence of Eu 2+ and Eu 3+ is achieved by controlling the Eu ions concentrations, sintering temperatures, and excitation wavelengths. Reduction and oxidation reactions of Eu ions were investigated by controlling the sintering atmospheres. XRD pattern indicated the typical amorphous glassy phase without obvious phase-separation even in high concentration (0.1 M). The presence of Eu 2+ ions, which were reduced from Eu 3+ by hole−electron pairs and diffused into mesoporous structure, was revealed by XPS spectra.
