The role of reaction conditions in the polymorphic control of Eu³⁺ doped YInO₃: structure and size sensitive luminescence

Abstract

Controlled synthetic conditions yielded YInO3:Eu3+ in both C-type and hexagonal modifications which exhibited a tremendous bearing of size and local structure on Eu3+ luminescence, all in a single compound.

Energy transfer dynamics and luminescence properties of Eu3+ in CaMoO4 and SrMoO4

“…5 (ESI †). The application of JO theory to the quantitative analysis of Eu 3+ emissive properties in matrix is nicely presented by Werts et al [65], and also by our group [11,16] and can be summarized as follow. It is calculated from the emission spectra and lower is this ratio; the higher is the site symmetry around europium ion.…”

“…However, self activated host emission without doping any activator ion (generally lanthanide) does takes place in various materials, and they transfer their excitation energy efficiently when certain lanthanide or for that say any activator ion is doped in that particular host [11].

An efficient gel-combustion synthesis of visible light emitting barium zirconate perovskite nanoceramics: Probing the photoluminescence of Sm 3+ and Eu 3+ doped BaZrO 3

“…This is schematically represented using Kroger-Vink notation as parameters is related to the bulk measurable such as viscosity and rigidity of the inorganic matrices [60]. The application of JO theory to the quantitative analysis of Eu 3 þ emissive properties in matrix is nicely presented by Werts et al [61], and also by our group [41,45] and can be summarized as follow. There is a close relationship between radiative emission rates and integral PL intensity for transition between two manifolds 5 D 0 and 7 F J (J ¼2, 4) can be written as: …”

“…We wanted to the probe the site occupancy of Eu 3 þ and Sm 3 þ through time resolved photoluminescence spectroscopy. Eu 3 þ is often used as a structural probe [41][42][43][44][45][46][47], because of the (a) relative simplicity of its energy-level structure and the fact that it possesses non-degenerate ground ( 7 F 0 ) and excited ( 5 D 0 ) states and (b) absorption and emission spectra of this ion show marked dependence on its site symmetry in the host material.The orange emission (590-600 nm) of Eu 3 þ due to the magnetic dipole transition (MDT) 5 D 0 -7 F 1 is not affected much by the site symmetry, because they are parity-allowed, while the red emission ( $ 610-630 nm) due to the electric dipole transition (EDT) of 5 D 0 -7 F 2 , being hypersensitive, is affected by the site symmetry of Eu 3 þ ion. In a crystal site inversion symmetry the EDT are strictly forbidden and the MDT are usually the dominant emission line.…”
