Radionuclide concentrations in raw and purified phosphoric acids from Brazil and their processing wastes: implications for radiation exposures
(Springer, 2012-02-01)
Radionuclides from the U and Th natural series are present in alkaline rocks, which are used as feedstock in Brazil for the production of raw phosphoric acid, which can be considered as a NORM (naturally occurring radioactive ...

Phosphor-based green-emitting coatings for circadian lighting
(2020-08-01)
Light-emitting diodes (LEDs) combining UV-emitting LEDs (UV-LED) with multi-coloured phosphors is one of the main strategies in solid-state lighting, opening new frontiers for the design of monochromatic sources. Greater ...
Determination of uranium in phosphoric acid using neutron activation analysis
(SPRINGER, 2009)
Phosphoric acid is generally obtained from an aqueous process starting with the reaction between phosphate rock and sulphuric acid. Due to their chemical similarity, uranium is usually associated with phosphate rock which ...
Synthesis, thermoluminescence, defect center and dosimetric characteristics of LiF:Mg,Cu,P,Si phosphor
(Pergamon-Elsevier Science Ltd, 2017)
LiF:Mg,Cu,P,Si (MCPS), a new tissue equivalent phosphor, was synthesized by solid state method. Powder x-ray diffraction and scanning electron microscope were employed to determine the structural features. The dosimetric ...
Luminescence and defect centres in MgSrAl(10)O(17):Sm(3+) phosphor
(ELSEVIER SCIENCE BV, 2010)
An efficient reddish orange emission MgSrAl(10)O(17):Sm(3+) phosphor was prepared by the combustion method. The phosphor has been characterized by X-ray diffraction, scanning electron microscopy, thermogravimetric analysis ...
Energy States of Phosphorous Donor in Silicon in Fields up to 18 T
(Springer/plenum Publishers, 2010-04-01)
The evolution of the energy states of the phosphorous donor in silicon with magnetic field has been the subject of previous experimental and theoretical studies to fields of 10 T. We now present experimental optical ...

Synthesis, Characterization, Luminescence and Defect Centres in CaYAl(3)O(7):Eu(3+) Red Phosphor
(SPRINGER/PLENUM PUBLISHERS, 2011)
CaYAl(3)O(7):Eu(3+) phosphor was prepared at furnace temperatures as low as 550A degrees C by a solution combustion method. The formation of crystalline CaYAl(3)O(7):Eu(3+) was confirmed by powder X-Ray diffraction pattern. ...
