Structural and optical properties of yttrium trioxide thin films prepared by RF magnetron sputtering

Electronic Structure and Optical Quality of Nanocrystalline Y2O3 Film Surfaces and Interfaces on Silicon

“…The best correlation between the experimental and calculated Ψ(λ), Δ(λ) curves (1) in Figure 7 is achieved at the best optical dispersion of Y x Si y O z interfacial oxide, as represented by curve (2) in Figure 8. The drastic difference, however, is evident between experimental points and Ψ(λ), Δ(λ) curves (2) in Figure 7 54 The dispersion is very strong over the spectral range of 200−500 nm and is practically absent at longer wavelengths. The results are not at all in correlation with the available dispersion properties of the Y 2 O 3 bulk.…”

“…Several optical models were tested for the Y 2 O 3 /Si layered system in the literature. The multilayer stack of (surface roughened Y 2 O 3 layer)–(Y 2 O 3 bulk layer)–(SiO 2 interface layer)–(Si substrate) was proposed in ref . However, a very strange refractive index dispersion has been found for the Y 2 O 3 oxide formed by Y 2 O 3 target sputtering in the (Ar + O 2 ) mixture .…”

Enhancement in hardness and transmittance of ZnS via SiO2/Y2O3 multilayer

“…In Fig. 4(a), the splitted spectrums is composed by two peaks locating at 156.7 and 158.8 eV bonding energy, which are corresponding to the standard peak position of Y3d 5/2 and Y3d 3/2 [12,13] and in Fig. 4(b), the splitted spectrums is locating at 528.8 eV and 531.5 eV bonding energy, which are corresponding to the standard peak position of O1s 3/2 and O1s 1/2 [12] related to Y-O bonding in Y 2 O 3 film.…”

“…Recently, in order to solve these two challenges, coating a protective and antireflective film on ZnS was commonly adopted by researchers; several materials were commonly chosen as protective and antireflective systems such as oxide [9], fluoride [10] and phosphide [11]. Among oxide, Y 2 O 3 and SiO 2 have attracted much attention from science community as their well environmental durability and high infrared transmittance [12][13][14].…”

Yttria-Coated Tungsten Fibers for Use in Tungsten Fiber-Reinforced Composites: A Comparative Study on PVD vs. CVD Routes

“…It is a ceramic material that is of great industrial and technological utility [19][20][21]. Yttria is an ideal candidate for the interface material for W f /W composites due to its good thermal and chemical stability [22,23]. Additionally, it shows low activation after neutron irradiation, which is particularly important for a fusion reactor [24].…”
