Journal ArticleDOI
Synthesis and characterization of YAG:Ce phosphors for white LEDs
TL;DR: In this paper, the developed techniques for producing phosphors with superior photoluminescence efficiency, including solid-state reaction, sol-gel and (co)precipitation methods, are reviewed.
Journal ArticleDOI
Synthesis and characterization of YAG:Ce,Gd and YAG:Ce,Gd/PMMA nanocomposites for optoelectronic applications
TL;DR: In this paper, a sol-gel method was developed to obtain cerium-, gadolinium-(co)activated yttrium aluminum garnet (YAG:Ce,Gd) phosphor.
Journal ArticleDOI
Antibacterial efficiency of cellulose-based fibers covered with ZnO and Al2O3 by Atomic Layer Deposition
Marian Popescu,Camelia Ungureanu,E. Buse,F. Nastase,Vasilica Tucureanu,Mirela Petruta Suchea,S. Draga,M.A. Popescu +7 more
TL;DR: In this paper, a conformal coatings with ZnO and Al2O3 of cotton and viscose fabrics were achieved by Atomic Layer Deposition (ALD) at low temperature, where the efficiency of the nanostructured layer is determined by its thickness, uniformity, configuration and adherence to the flexible substrate.
Journal ArticleDOI
Synthesis and characterization of Ca doped ZnO thin films by sol–gel method
Anca-Ionela Istrate,F. Nastase,Iuliana Mihalache,Florin Comanescu,Raluca Gavrila,Oana Tutunaru,Cosmin Romanitan,Vasilica Tucureanu,Monica Nedelcu,Raluca Muller +9 more
TL;DR: In this article, the structural changes in the molecular binding between ZnO and Ca, Fourier Transform Infrared spectroscopy (FTIR), Micro-Raman Spectroscopy and X-ray diffraction (XRD) were performed.
Journal ArticleDOI
