Yttrium oxysulfide nanosized spherical particles doped with Yb and Er or Yb and Tm: efficient materials for up-converting phosphor technology field
(Elsevier B.V., 2004-07-14)
This work reports on the preparation, structural and luminescent studies of nanosized up-converter phosphors Y2O2S:Yb(4%), Er(0.1%) and Y2O2S:Yb(4%), Tm(0.1%),both from polymeric and basic carbonate precursors. The precursors ...

Derivation and validation of a hard-body particle-wall collision model for non-spherical particles of arbitrary shape
(Elsevier, 2021-03)
In this work an extended three-dimensional model to describe the process of wall collisions of arbitrary shaped non-spherical particles is developed. This model is derived as the generalized solution of the hard-sphere ...
Scattering of clusters of spherical particles-Modeling and inverse problem solution in the Rayleigh-Gans approximation
(Elsevier, 2013-05-25)
In this work, an exact scattering model for a system of clusters of spherical particles, based on the Rayleigh-Gans approximation, has been parameterized in such a way that it can be solved in inverse form using Thikhonov ...
The effect of EU3+ ion doping concentration in Gd2O3 fine spherical particles
(Elsevier B.V., 2002-10-07)
This work reports on the preparation of Gd2O3, cubic system, with spherical particles, narrow size distribution, whether or not doped with 1-5 at.% of Eu3+ and the influence of Eu3+ concentration on optical and morphological ...

Particle scattering in the rayleigh-debye- gans regime: Applications to polymer latexes and polymer-polymer concentrated dispersions
(Research Singpost, 2010)
In this chapter we have given an overview of the Rayleigh-Debye-Gans (RDG) theory applied in the analysis of Small Angle Scattering (SAS) data of different types of particle systems. First some useful derivations needed ...
