One-step synthesis of MFe2O4 (M=Fe, Co) hollow spheres by template-free solvothermal method

Perpendicular magnetic anisotropy in 70nm CoFe2O4 thin films fabricated on SiO2/Si(100) by the sol–gel method

“…[1][2][3][4][5][6][7][8]. The modification of magnetic and dielectric properties of CFO can be realized through substitution [9][10][11], fabrication of monodispersed purified hollow ferrite spheres [12] and growth of CFO films on different substrates using various techniques such as sputtering, molecular beam epitaxy, pulsed laser deposition and sol-gel method [3,4,[13][14][15][16][17][18][19][20][21][22][23][24][25][26][27]. Considering practical applications in magnetic recording, the sol-gel method is an attractive alternative to other deposition methods due to its advantages such as lower annealing temperature, easier composition control, non-vacuum process and easier fabrication of large area thin films [21,23].…”

Gd2O2S:Eu3+ and Gd2O2S:Eu3+/Gd2O2S hollow microspheres: Solvothermal preparation and luminescence properties

“…Yermolayeva et al [12] presented the preparation of Lu 2 O 3 :Eu 3+ submicrometer spherical phosphors by the homogeneous precipitation technique with subsequent annealing for spheres crystallization. Meanwhile, monodisperse hollow spheres have been receiving great attention, since these materials can be dispersed well, enhance the uniformity, give high packing densities of the coating, and achieve a reduction in the amount of expensive rare earth metals [13][14][15][16][17][18]. Definitely, owing to the excellent characteristics, the hollow spheres of rare earth doped phosphors hold great promise for applications such as MR imaging, diagnostic analysis, fluorescent labeling and drug delivery carriers.…”

Template-free synthesis of Cd(OH)2 hollow spheres and its optical properties

“…Due to their special structure, unique optical properties, low density, large surface area, stability and surface permeability, hollow spheres with nanometer-to-micrometer dimensions are potentially useful in a wide range of applications such as photonic crystals, delivery vehicle system, containers for encapsulation, catalysts, and protection of biologically active agents like proteins, enzymes or DNA, fillers and controlled release capsules for drugs, etc. [1][2][3][4][5][6][7].…”
