Synthesis and characterization of nanocrystalline Yb:Lu2O3 by modified Pechini method

Preparation of Yb2O3 submicron- and nano-materials via electrospinning

“…The preparation and study of submicron and nanocrystalline oxides containing lanthanides are currently an important area in materials research [1][2][3][4][5]. Lanthanide oxides are widely used in a range of technological applications, like electronics, technical ceramics, catalysts, colored glasses, phosphors, laser materials and polishing powders for optics [6].…”

“…It is the case of the catalytic activity that increases with the porosity and the reduction of the grain size, as a consequence of enlarged specific surface area [7]; the wavelength of luminescent materials is as well a function of the grain dimensions, due to quantum confinement effects [8,9]. Therefore, several methods have been developed for the preparation of lanthanide oxides as submicron and nanocrystalline materials [1][2][3][4][5].…”

Traps Formation and Characterization in Long-Term Energy Storing Lu2O3:Pr,Hf Luminescent Ceramics

“…These findings shall not be presented here, as analogous results for Lu 2 O 3 powders and ceramics were frequently published in recent years. [22][23][24] ceramics. The excitation spectra of the Pr 3+ emissions is dominated by broad bands around 300 nm resulting from the 4f→5d absorption of Pr 3+ as already identified in 25 .…”

Synthesis and luminescent properties of CaLa2ZnO5:Ln (Ln:Tm3+ or Er3+) phosphors

“…Among them, the citrate sol-gel method is one of the best methods for synthesizing efficient phosphor materials. This synthetic route offers the use of different temperatures and proportions of citric acid and metallic cations for producing nanometric powders with compositional homogeneity and controlling the particle size and morphology [9,21,22]. Herein, Tm 3 þ or Er 3 þ ions singledoped CLZO phosphors were prepared by the citrate sol-gel method for the development of blue and green emissions with good chromaticity coordinates.…”
