Synthesis, characterization and formation mechanism of dumbbell-like YOHCO3 and rod-like Y2(CO3)3·2.5H2O

Microwave assisted synthesis of monodispersed Y2O3 and Y2O3:Eu3+ particles

“…\Àt2 À (CO υ as ) is around 1085 cm À 1 , while the absorptions peaks at 850, 836 cm À 1 and 728, 712 cm À 1 are assigned to deformation vibration of C-O (CO δ) and their splitting [36,37]. There are no absorption bands observed for HCO 3 À and NO 3 \Àt À groups in the spectra suggesting the composition of the as prepared particles are Y(OH)CO 3 and they maintain the same structure till 300 1C [9].…”

Synthesis of Yttria Nanopowders by Two Precipitation Methods and Investigation of Synthesis Conditions

“…Yttria finds potential application because of its high corrosion resistivity, thermal stability, and transparency over a wide wavelength region, that is, violet to infrared light. Depending of the application, a wide range of quality may be needed for the powder . Yttria has outstanding properties such as high melting point, excellent chemical stability, and low volatility in vacuum.…”

Preparation and luminescence characterization of new carbonate (Y2(CO3)3·nH2O:Eu3+) phosphors via the hydrothermal route

“…Hence, rare earth ions incorporated with aluminates [4], borates [5], and silicates [6] have been widely used as phosphors. Besides above materials, carbonate is another interesting host because of its thermal luminescence properties [7]. However, the luminescence properties of the carbonate-based phosphors are not investigated in details.…”

“…Various techniques, such as the homogeneous precipitation method [9], the hydrothermal method [7], and the gel method [8], have been developed to prepare Y 2 (CO 3 ) 3 ·nH 2 O. The reaction time of all above methods was needed at least for 2 days, and the crystallinity of obtained powders was insufficient.…”

“…The hydrothermal process not only shortens the required reaction time, but also lowers the temperature for synthesizing ceramic powders [10][11][12]. Additionally, employing urea as a precipitant is reportedly crucial to synthesize carbonate-based powders with a uniform morphology [7].…”
