“…PL emission can be used to analyse the effectiveness of migration, charge carrier entrapment, and the destiny of photogenerated electron-hole pairs in semiconductors [18–20]. Because PL emission caused excited electron-hole pairs to recombine, effective separation of charge carrier resulted in a decrease in PL intensity [21, 22].…”

“…The XPS technique was used to evaluate the elemental composition, chemical states, and elemental bonding for in semiconductors [18][19][20]. Because PL emission caused excited electron-hole pairs to recombine, effective separation of charge carrier resulted in a decrease in PL intensity [21,22]. A PL excitation (PLE) spectrum of 3 mol% Dy 3+ -doped ZrO 2 nanophosphor measured at a fixed emission wavelength of 580 nm corresponds to the electronic transition ( 4 F 9/22 ➔ 6 H 13/2 ).…”

Solution combustion was employed to create a series of ZrO2:Dy3+ (1-11 mol percent) nanoparticles (NPs) using oxalyl dihydrazide (ODH) as the fuel. ZrO2:Dy3+ NPs were subjected to calcination at about 700°C. ZrO2:Dy3+ NPs comprised of 1 to 11 mol% of Dy3+ were characterized by employing the X-ray diffraction (XRD), transmission electron microscopic (TEM), UV-visible, and X-ray photoelectron spectroscopic (XPS) techniques. The crystallite diameters of 1 to 11 mol% ZrO2:Dy3+ NPs were observed to range from 8.1 nm to 16.3 nm, exhibiting spherical shape. According to BET tests, the pore volume of ZrO2:Dy3+ NPs was determined to be 100.129 cm3/g. The mean pore diameter of ZrO2:Dy3+ NPs was determined to be 4.803 nm from the Barrett-Joyner-Halenda (BJH) plot. The photoluminescence and photocatalytic dye degradation properties of ZrO2:Dy3+ NPs were investigated. The acid red 88 (AR88) dye was applied to appraise the photocatalytic activities of the NPs under UV irradiation. ZrO2:Dy3+ NPs with 3 mol% Dy3+ exhibited improvised photocatalytic activity due to the operative departure of charge carriers. The electrochemical examination of ZrO2:Dy3+ NP modified carbon paste electrode in 0.1 N HCl demonstrated considerable redox potential output, as evidenced by cyclic voltammetric and amperometric measurements. The electrochemical sensor studies on ZrO2:Dy3+ NPs exhibited potentiality towards sensing of highly toxic metals like mercury and lead.

“…Zirconium dioxide is a wide-gap dielectric (E g = 5–7 eV), which has high mechanical (strength, refractoriness, corrosion resistance), as well as functional (transparency in a wide range of wavelengths, high refractive index, high ionic conductivity) properties. These properties determine the wide possibilities of using ZrO 2 in industry as a material for electrochemical devices, and oxygen sensors [ 1 , 2 , 3 , 4 ], as well as materials for photocatalysis [ 5 , 6 , 7 , 8 , 9 ] and optical devices [ 10 , 11 , 12 , 13 , 14 , 15 , 16 , 17 ]. The optical and luminescent properties of this material are largely determined by the presence of structural defects, which is especially important when it is used in conditions of harsh radiation environments (nuclear power plants, space electronics).…”

Paramagnetic Defects and Thermoluminescence in Irradiated Nanostructured Monoclinic Zirconium Dioxide

The ESR spectra of nanostructured samples of monoclinic ZrO2 irradiated by electrons with energies of 130 keV, 10 MeV, and by a beam of Xe ions (220 MeV) have been studied. It has been established that irradiation of samples with electrons (10 MeV) and ions leads to the formation of radiation-induced F+ centers in them. Thermal destruction of these centers is observed in the temperature range of 375–550 K for electron-irradiated and 500–700 K for ion-irradiated samples. It is shown that the decrease in the concentration of F+ centers is associated with the emptying of traps responsible for thermoluminescence (TL) peaks in the specified temperature range. In the samples irradiated with an ion beam, previously unidentified paramagnetic centers with g = 1.963 and 1.986 were found, the formation of which is likely to involve Zr3+ ions and oxygen vacancies. Thermal destruction of these centers occurs in the temperature range from 500 to 873 K.
