“…Some trap levels and shallow centres of oxygen vacancies in the bandgap of Ta 2 O 5 corresponding to light emission ranging from green to red wavelengths have been reported [10][11][12]. In addition, light emission ranging from blue to red wavelengths was also observed from Y 2 O 3 [13]. Therefore, the broad PL spectra from Ta 2 O 5 :Y 2 O 3 films annealed at 700°C in Fig.…”

a b s t r a c tCo-sputtered tantalum (V) oxide and yttrium (III) oxide (Ta 2 O 5 :Y 2 O 3 ) thin films were fabricated using radio-frequency magnetron sputtering for the first time, and their photoluminescence (PL) and X-ray diffraction properties were evaluated. Broad PL spectra from 380 to 800 nm were observed only from films annealed at 700°C. The maximum PL intensities were found around a wavelength of 500 nm regardless of the Y concentrations of the films, and the films annealed at 700°C were primarily amorphous phases. It seems that the broad PL spectra from the Ta 2 O 5 :Y 2 O 3 films originated from oxygen vacancies of Ta 2 O 5 and Y 2 O 3 particles that may be produced in Ta 2 O 5 by co-sputtering.

Y(2)O(3) dumbbells, microspheres, and nanosheets were synthesized by a facile hydrothermal procedure followed by calcination. Electron microscopy, X-ray diffraction, and N(2) adsorption measurements were used to characterize the yttrium oxide microstructures. On the basis of a time-dependent study of nanostructure evolution and the effect of other processing parameters, a kinetic "homogeneous nucleation-self assembly-anisotropic growth" mechanism is proposed to explain the growth of these microstructures under hydrothermal conditions. The sensitivity of as-prepared Y(2)O(3) structures to a series of gaseous chemicals was examined by using a homemade cataluminescence sensing system. The designed cataluminescence sensor based on the yttrium oxide dumbbells shows good sensing performance for 16 common volatile organic compounds.
