Urea Glass Route as a Way to Optimize YAGG:Ce,Cr,Pr Nanocrystals for Persistent Luminescence Applications.

A new approach for the synthesis of YAlGaO (YAGG) nanophosphors allowing the preparation of crystallites with sizes starting from 45 nm is presented. The controllability of the energy and trap density of the resulting material samples by annealing temperature was confirmed by thermoluminescence (TL) measurements. It has been shown that the annealing of samples at temperatures up to 1300 °C does not cause any substantial growth of crystallites, still remaining below 100 nm, but leads to changes in the activation energy of the persistent luminescence (PersL) process.

Size-Dependent Persistent Luminescence of YAGG:Cr Nanophosphors.

In the current work, YAGG:Cr nanophosphors were synthesized by the Pechini method and then annealed at different temperatures in the range 800-1300 °C. The structure and morphology of the samples were characterized by X-ray Powder Diffraction (XRPD). The lattice parameters and average crystalline sizes as site occupation by Al and Ga ions were calculated from the Rietveld refinement data.

Efficacy and Safety of Imatinib in Paediatric CML - A Single Centre Study.

Background/aim: Chronic myeloid leukaemia (CML) rarely affects the paediatric population and has an incidence of 0.06-0.12/100,000 children per year.

Structural and optical characterization of RbLaPO:Ln (Ln = Ce, Nd, Tm, or Yb).

In this work, for the first time, detailed structural and optical characterization of RbLaPO doped with different concentrations of Ce, Nd, Tm, or Yb ions is reported. The samples were obtained via a precipitation technique. Their structural characterization was performed using X-ray diffraction (XRD), and infrared and Raman spectroscopies.
