“…Due to the presence of a large gap between the 5 D 0 level and the next-lower manifold (∼12,000 cm −1 ), there is the highest probability of energy transfer from the 5 D 0 level to the other level of the second element [ 46 ]. One of these elements can be neodymium or ytterbium ions which exhibit luminescence spectra in the first and second biological windows [ 47 , 48 , 49 , 50 ]. Neodymium ions (Nd 3+ ) have emission bands at the wavelengths of 890 nm ( 4 F 3/2 → 4 I 9/2 ) and 1060 nm ( 4 F 3/2 → 4 I 11/2 ) [ 45 , 51 ].…”

Nanophosphors are widely used, especially in biological applications in the first and second biological windows. Currently, nanophosphors doped with lanthanide ions (Ln3+) are attracting much attention. However, doping the matrix with lanthanide ions is associated with a narrow luminescence bandwidth. This paper describes the structural and luminescence properties of co-doped LaPO4 nanophosphors, fabricated by the co-precipitation method. X-ray structural analysis, scanning electron microscope measurements with EDS analysis, and luminescence measurements (excitation 395 nm) of LaPO4:Eu3+/Nd3+ and LaPO4:Eu3+/Nd3+/Yb3+ nanophosphors were made and energy transfer between rare-earth ions was investigated. Tests performed confirmed the crystal structure of the produced phosphors and deposition of rare-earth ions in the structure of LaPO4 nanocrystals. In the range of the first biological window (650–950 nm), strong luminescence bands at the wavelengths of 687 nm and 698 nm (5D0 → 7F4:Eu3+) and 867 nm, 873 nm, 889 nm, 896 nm, and 907 nm (4F3/2 → 4I9/2:Nd3+) were observed. At 980 nm, 991 nm, 1033 nm (2F5/2 → 2F7/2:Yb3+) and 1048 nm, 1060 nm, 1073 nm, and 1080 nm (4F3/2 → 4I9/2:Nd3+), strong bands of luminescence were visible in the 950 nm–1100 nm range, demonstrating that energy transfer took place.

“…Depending on the chemical composition, the 1111-phases can reveal the variations of a number of physical characteristics (such as electrical and thermal conductivity, some optical and magnetic properties, etc) in a wide range, and therefore they are of interest for various fields of modern materials science. For instance, as non-linear optic materials (LaCuSO, LaCuSeO) for various optoelectronic applications [3][4][5][6][7], materials for solar cells (LaZnPO:Nd 3+ [8]), ferro-and antiferromagnetic semiconductors (LaCu 1-x Mn x SeO, LaMnPO [9][10][11]) or even the solids with non-collinear magnetic structure (some compounds with 4f-metals), thermoelectric materials (BiCuSO, BiCuSeO [12,13]) and so on. Besides, some non-magnetic 1111-phases can be proposed as the initial crystalline matrices for design of novel magnetic materials with abilities of "fine tuning" of their functional properties by means of the corresponding choice of dopants (see [14] and References therein).…”

The comparative study of structural, electronic properties, topology of the Fermi surface, and the features of chemical bonding in layered 1111-oxyarsenides LaRhAsO and LaIrAsO has been performed based on the results of ab initio modeling of their electronic structure. It was established that only weak sensitivity with respect both to electron and hole doping is expected for LaIrAsO being non-magnetic metal, however, the Rh-containing compound should be characterized with weak band magnetism, and the hole doping is expected to be able to move its ground state away from the boundary of magnetic instability. The mentioned feature allows to consider LaRhAsO oxyarsenide as a possible "electron analogue" of LaFeAsO compound being the initial phase for the layered FeAs-superconductors.
