“…Yttrium oxide (Y 2 O 3 ) is one of the most important advanced ceramic materials that has been investigated for many application areas such as ceramics, optics, magnets, catalysts, superconductors, insulators, and sensors [1]. In addition, Y 2 O 3 is a promising host matrix for various triply ionized lanthanide ions (Ln 3 þ ) for phosphor industry.…”

“…As is well known, inorganic particles show unique size-dependent and shape-dependent properties. Over the past years, yttrium oxide, with various morphologies and sizes, has been prepared by many researchers [1][2][7][8][9][10][11] and our group [12][13][14][15][16]. As expected, these microstructures and nanostructures lead to interesting shape-dependent properties and wide potential applications.…”

“…Y 2 O 3 with controllable sizes and morphologies is usually prepared after thermal treatment of its precursor at high temperature. The most familiar precursor is hexagonal Y(OH) 3 [12][13][14][15][16]. Y 2 (OH) 5 [20] were also reported as precursors.…”

In this work, a facile route using a simple solvothermal reaction and sequential heat treatment process to prepare porous Y 2 O 3 microcubes is presented. The as-synthesized products were characterized by X-ray powder diffraction (XRD), scanning electronic microscope (SEM), energy dispersive spectrometer (EDS), thermogravimetric analysis (TG), and differential thermal analysis (DTA). The thermal decomposition process of the Y 2 O 3 precursor was investigated. SEM results demonstrated that the as-prepared porous Y 2 O 3 microcubes were with an average width of about 20 µm and thickness of about 8 µm. It was found that the morphology of the Y 2 O 3 precursor could be readily tuned by varying the molar ratio of 2 2 8 S O − to Y 3+ . Y 2 O 3 :Eu 3+ (6.6%) microcubes were also prepared and their photoluminescence properties were investigated.

“…The nanosized phosphors also present similar size dependence of luminescence [10,[12][13][14][15][16], including novel 5 D 0 → 7 F 2 emission band, shift of the charge transfer band (CTB), short fluorescence lifetime, and high quenching concentration. However, there is much controversy about (1) shift direction of CTB [15][16][17][18][19] and (2) blue shift of emission peaks [16,20,21].…”

“…The latest developments include but are more than these: the influence of codoping various metal ions [7][8][9], the effect of surface modification on nanoparticles [10], the control of the nanocrystal shape via various synthesis methods [11][12][13][14]. Among the materials, Re 2 O 3 :Eu (Re = Y, Gd, Lu) are typical, as Eu 3+ is hypersensitive to its configuration circumstance and plays the role of probe ion.…”
