Luminescence performance of europium-doped yttrium oxide thin films

Preparation and photoluminescence of yttrium hydroxide and yttrium oxide doped with europium nanowires

Single-crystalline Y(OH)3:Eu nanowires have been prepared by polymer-assisted hydrothermal method. The yields of the nanowires were higher than 95%. XRD patterns showed that the products were the hexagonal Y(OH)3 structure. SEM images displayed that the nanowires consisted of nanobelts and nanorods. The nanorods have the diameter of about 85 nm and length up to several tens of microns, and the ...

Cathodoluminescence Study of Gadolinium–Doped Yttrium Oxide Thin Films Deposited By Radio–Frequency Magnetron Sputtering

A multi–layer gadolinium–doped yttrium oxide thin film was deposited in a combinatorial fashion on a Si (001) substrate using radio–frequency magnetron sputtering. Alternating layers of Y2O3 and Gd were deposited for a total of 9 layers. The film was homogenized in composition by an 850 C 12 hour thermal treatment producing a range of composition from Y1.96Gd0.04O3 – Y1.54Gd0.46O3 in a single f...

Fatigue mechanism of yttrium-doped hafnium oxide ferroelectric thin films fabricated by pulsed laser deposition.

Owing to their prominent stability and CMOS compatibility, HfO2-based ferroelectric films have attracted great attention as promising candidates for ferroelectric random-access memory applications. A major reliability issue for HfO2 based ferroelectric devices is fatigue. So far, there have been a few studies on the fatigue mechanism of this material. Here, we report a systematic study of the f...

Visible Luminescence of Rare Earth Ions Doped Amorphous Zinc Oxide Thin Films Grown by Sputtering Technique

Deposition of yttrium oxide thin films in supercritical carbon dioxide

A synthetic avenue for the formation of yttrium oxide thin films on Si native oxide surfaces is demonstrated by the reaction of Tris(2,2,6,6tetramethyl-3,5-heptanedionato) yttrium(III) with inorganic (H2O2) and organic (tert-butyl and di-tert-amyl) peroxides in supercritical carbon dioxide. The reactions are carried out in a hot wall reactor at temperatures below 130 °C and pressures ranging fr...
