Controlled synthesis and tunable luminescence of uniform YPO₄·0.8H₂O and YPO₄·0.8H₂O : Tb³⁺/Eu³⁺ nanocrystals by a facile approach

Abstract

The emission spectra of Y0.96−xPO4·0.8H2O : 0.04Tb3+, xEu3+ (x = 0–0.18) nanocrystals could result in tunable emission with self-activated luminescence and rare earth-doping emission.

Quick synthesis, functionalization and properties of uniform, luminescent LuPO4-based nanoparticles

“…2,5 Many research groups have reported, in the last decade, on the doping of YPO 4 , LaPO 4 , CePO 4 , and GdPO 4 nanoparticles with ions of the f-elements for optoelectronic as well as biotechnological applications. [6][7][8][9][10][11][12][13] However, very few reports have been found in the literature which describe the synthesis of LuPO 4 particles. Gao et al 14 reported the synthesis of uniform LuPO 4 hollow spheres using a two-step urea-based process which rendered particles with a diameter of around 300 nm, well above the size of nanometer-scale materials.…”

Influence of citrate on phase transformation and photoluminescence properties in LaPO4 and LaPO4:Eu

“…22,23 Actually, citrate is oen used as a structure-directing agent to control the nucleation, growth and alignment of REPO 4 crystals. 24,25 In order to achieve the phase transformation of REPO 4 compounds at low temperature, the organic ligand-induce might be a feasible method.…”

Luminescence properties of neodymium, samarium, and europium niobate and tantalate thin films

“…Europium Eu 3+ ion is utilized as a red‐emitting actuator in commercial phosphors, this is attributed to the 5 D 0 → 7 F J (J = 1–6) transitions in the red spectral region. [ 17,19 ] Graca et al . [ 20 ] described the luminescence properties of the EuNbO 4 and its intense red emission and the formation of multiple Eu 3+ optical active centres.…”
