X-ray excited luminescence of SrAl2O4:Eu,Dy at low temperatures
(Elsevier B.V., 2018)
Particle size effects on the structure and emission of Eu3+:LaPO4 and EuPO4 phosphors
(Elsevier B.V., 2018)
This paper provides the detailed study of (nano)particle's size effect on structural and luminescent properties of LaPO4:Eu3+ synthesized by four different methods: high temperature solid-state, co-precipitation, reverse ...
High resolution luminescence spectroscopy and thermoluminescence of different size LaPO4:Eu3+ nanoparticles
(Elsevier B.V., 2018)
Nanoparticles (5 nm) and nanorods (2 nm × 15 nm and 4 nm × 20 nm) of monoclinic monazite LaPO4:Eu3+ were prepared by reverse micelle and co-precipitation techniques. Effects of the particle size and surface defects on the ...
Development, Characterization, and Testing of a SiC-Based Material for Flow Channel Inserts in High-Temperature DCLL Blankets
(Institute of Electrical and Electronics Engineers Inc., 2018)
Flow channel inserts (FCIs) are the key elements in the high-temperature dual-coolant lead-lithium blanket, since in this concept the flowing PbLi reaches temperatures near 700 °C and FCIs should provide the necessary ...
Mechanical reinforcement of electrospun poly(vinyl alcohol) by α‐FeOOH nanowires
(Society of Plastics Engineers (SPE), 2018)
We report the mechanical performance of α‐FeOOH nanowire reinforced poly(vinyl alcohol) (PVA) composite nanofiber mat, fabricated using straightforward aqueous processing methods. Goethite (α‐FeOOH) nanocrystals have a ...
Depth profiles of aggregate centers and nanodefects in LiF crystals irradiated with 34 MeV 84Kr, 56 MeV 40Ar and 12 MeV 12C ions
(Elsevier B.V., 2018)
Depth profiles of nanohardness and photoluminescence of F2 and F3 + centers in LiF crystals irradiated with 12 MeV 12C, 56 MeV 40Ar and 34 MeV 84Kr ions at fluences 1010–1015 ions/cm2 have been studied using laser scanning ...
Solvothermal synthesis derived Co-Ga codoped ZnO diluted magnetic degenerated semiconductor nanocrystals
(Elsevier Ltd, 2018)
Here we are reporting solvothermal synthesis derived diluted magnetic and plasmonic Co-Ga co-doped ZnO nanocrystals with high magnetization values (from 1.02 to 4.88 emu/g) at room temperature. Co-Ga co-doped ZnO nanocrystals ...
Synthesis, structure and spectroscopic properties of luminescent GdVO4:Dy3+ and DyVO4 particles
(Elsevier B.V., 2018)
In this work, we focused on the syntheses, structure and spectroscopic properties of GdVO4:Dy3+ and DyVO4 (nano)particles of different sizes and shapes (spherical nanoparticles of 2 nm, 4 nm, and 20 nm in size, nanorods ...
Reversible Photodoping of TiO2 Nanoparticles for Photochromic Applications
(American Chemical Society, 2018)
Observations on the strong photochromic effect of crystalline TiO2 quantum dots (mean size ≈ 4 nm) are presented. The synthesized quantum dots consist of irregularly shaped anatase TiO2 nanoparticles (NPs) and are dispersed ...
Structural, optical, and luminescence properties of ZnO:Ga optical scintillation ceramic
(OSA - The Optical Society, 2018)
This paper discusses the characteristics of ZnO and ZnO:Ga ceramics fabricated by uniaxial hot pressing. The short-wavelength transmission limit of zinc oxide ceramics is in the 370-nm region; the long-wavelength limit is ...
