Low temperature synthesis of pure cubic ZrO2 nanopowder: Structural and luminescence studies

Facile green fabrication of iron-doped cubic ZrO2 nanoparticles by Phyllanthus acidus: Structural, photocatalytic and photoluminescent properties

“…Several materials possess the band gap energies which are suitable for promoting a wide range of photochemical reactions [2]. Among the various semiconductors, Zirconia (ZrO 2 ) is an n-type semiconductor with band gap ∼ 5.0 eV and was widely employed as a raw material in textiles, cosmetics, ceramics, solid oxide fuel cell electrolytes, gas sensors and optical devices [3][4][5][6][7][8][9]. It has high optical transparency, high refractive index, good thermal stability, low coefficient of thermal expansion, low thermal conductivity, high melting point, high chemical stability and polymorphic nature [10,11].…”

Phase transformation of ZrO2:Tb3+ nanophosphor: Color tunable photoluminescence and photocatalytic activities

“…The luminescent properties of these nanomaterials make them attractive for many technological applications like display devices, up-conversion solar cells, white-light generation and detectors in medical diagnosis equipments [9]. Considerable efforts have been dedicated to develop new single host WLED phosphors using oxide, oxyfluoride, nitride, oxy-nitride, sulfide and halide hosts [10][11][12][13][14][15][16][17] Among different oxide host materials, zirconia is an attractive material in both fundamental and application oriented research. Zirconia exists in three crystalline phases, viz., monoclinic (<1443 K), tetragonal (1443-2643 K) and cubic (>2643 K) [18].…”

Effect of fuels on conductivity, dielectric and humidity sensing properties of ZrO2 nanocrystals prepared by low temperature solution combustion method

“…The characteristic strong broad peak observed at 3445 cm −1 is attributed to the presence of physically adsorbed moisture. The strong peak at 1634 cm −1 is due the bending vibrations of chemisorbed H 2 O molecules [9,41]. The intense peak at 1382 cm −1 was also observed in both the samples and it is strong and more intense in ZrO 2 -2.…”

“…Mostly the cubic phase of zirconia is stabilized by doping with dopants [10]. However, recently Prakashbabu et al have reported the synthesis of pure cubic ZrO 2 without the aid of any stabilizing agents such as yttrium [9]. Several synthetic approaches such as mechanochemical processing, sol-gel, thermal decomposition, ionic-liquid route, hydrothermal synthesis, spray pyrolysis, and emulsion precipitation [11][12][13][14][15][16][17] have been employed to prepare ZrO 2 nanocrystals.…”

“…The choice of fuel significantly impacts the exothermicity and amount of gases that evolve during the combustion process; this in turn has a strong influence on the properties of the product [21]. The fuels employed so far in the combustion synthesis of ZrO 2 are citric acid [22], glycine [23], and ODH [9]. Hence by approaching with different fuels for the synthesis of ZrO 2 , the conductivity studies and dielectric studies have been carried out.…”
