A comparison between neodymium doped alumina samples obtained by Pechini and sol-gel methods using thermo-stimulated luminescence and SEM
(ELSEVIER SCIENCE BV, 2010)
Neodymium doped and undoped aluminum oxide samples were obtained using two different techniques: Pechini and sol-gel. Fine grained powders were produced using both procedures, which were analyzed using Scanning Electron ...
Thermo luminescence and optically stimulated luminescence characteristics of Al2O3 doped with Tb
(Elsevier B.V., 2014-12-01)
In the present work policrystals of alpha - Al2O3 doped with terbium were synthesized using the solvent evaporation method. the samples were prepared using Al(NO3)(3)center dot 9H(2)O and Tb(NO3)(3).5H(2)O reagents, with ...
Thermo- radio- and optically stimulated luminescence of Ce-doped KYF4 single crystals
(Pergamon-Elsevier Science Ltd, 2019-10)
The goals of this work are to determine the luminescence properties of KYF4 single crystals doped with different concentrations of Ce3+ ions and to evaluate their possible application as a detector of beta radiation. In ...
Bacterial cellulose and silk fibroin biopolymers: biotemplates to design nanostructured materials for optical applications
(Universidade Estadual Paulista (Unesp), 2016-10-04)
Among all natural polymers, bacterial cellulose and silk fibroin offer unlimited opportunities for processing, functionalization, and biological integration. This thesis presents the preparation and characterization of ...
