Lanthanide-doped orthovanadate phosphors: Syntheses, structures, and photoluminescence properties
(Woodhead Publishing, 2020)
A comprehensive systematic review is given of developments, trends, and advances over the past two decades in research on orthovanadates of monovalent, divalent, and trivalent metals, MI3VO4, MII3(VO4)2, and MIIIVO4, ...
Highly-increased photoluminescence of Pr3+ due to the Eu2+→ Pr3+ energy transfer in Al2O3 coatings formed by plasma electrolytic oxidation
(Journal of Luminescence, 2020)
In this paper, photoluminescence (PL) properties of Pr3+ single doped and Pr3+/Eu2+ co-doped Al2O3 coatings formed by plasma electrolytic oxidation of aluminum were investigated. The PL spectra of Al2O3:Pr3+ coatings feature ...
NMR relaxometric properties and cytotoxicity of Gd2O3 nanoparticle suspensions in an organic liquid
(Journal of Nanoparticle Research, 2014)
Gd2O3 nanoparticles and their agglomerates from approximately 10 to 80 nm in size suspended in an organic liquid were synthesized via polyol route. The reaction between diethylene glycol and added acetic acid, which occurred ...
Chapter 4 - Upconversion photoluminescence properties of ZrO2: Ln3+/Yb3+ (Ln = Er, Ho, Tm) films formed by plasma electrolytic oxidation
(Upconversion Nanophosphors, 2022)
The highly-efficient upconversion photoluminescent ZrO2:Ln3+/Yb3+ (Ln = Er, Ho, Tm) films were prepared by the plasma electrolytic oxidation method from the pure zirconium foil, by adding Ln2O3 and Yb2O3 particles to the ...
Ternary NR/BR/SBR rubber blend nanocomposites
(Journal of Thermoplastic Composite Materials, 2018)
The goal of this work was to synthesize and characterize ternary rubber blends based on polyisoprene (natural rubber (NR)), polybutadiene rubber (BR), and styrene-butadiene rubber (SBR) (NR/BR/SBR = 25/25/50) reinforced ...
Photoluminescence properties of nano-sized (Lu1-xYx)PO4:Pr3+ (x = 10, 20, 30, 40, 50 at. %) phosphor powders
(Optical Materials, 2020)
Herein we present the enhancement of photoluminescence properties of nano-sized LuPO4:Pr3+ phosphor powders synthesized by sol gel process with incorporation of yttrium ions inside of this single matrix to obtain ...
Particle size effects on the structure and emission of Eu3+: LaPO4 and EuPO4 phosphors
(Journal of Luminescence, 2018)
This paper provides the detailed study of (nano) particles size effect on structural and luminescent properties of LaPO4: Eu3+ synthesized by four different methods: high temperature solid-state, co-precipitation, reverse ...
Mechanical properties and thermal aging behaviour of polyisoprene/polybutadiene/styrene-butadiene rubber ternary blend reinforced with carbon black
(Composites: Part B: Engineering, 2016)
The goal of this work was to study thermal aging of sulfur cured ternary blends based on polyisoprene (NR), polybutadiene (BR) and styrene butadiene rubber (SBR) (NR/BR/SBR=(25/25/50) reinforced with different loading ...
Relationship between method of anastomosis and anastomotic failure after right hemicolectomy and ileo-caecal resection: an international snapshot audit
(Colorectal Disease, 2017)
Aim The anastomosis technique used following right-sided colonic resection is widely variable and may affect patient outcome. This study aimed to assess the association between leak and anastomosis technique (stapled vs ...
Surface State-Induced Anomalous Negative Thermal Quenching of Multiferroic BiFeO3 Nanowires
(Physica Status Solidi - Rapid Research Letters, 2018)
Wide-bandgap semiconductor nanowires with surface defect emission centers have the potential to be used as sensitive thermometers and optical probes. Here, we show that the green luminescence of multiferroic BiFeO3 (BFO) ...
