Effects of the wet air on the properties of the lanthanum oxide and lanthanum aluminate thin films

One-pot, template-free synthesis of hydrophobic single-crystalline La(OH)3 nanowires with tunable size and their d0 ferromagnetic properties

“…9,15-20 However, it is still a big challenge to precisely control the size, purity, compositions and crystal structures of 1D nanomaterials on the nanoscale in the absence of catalysts and templates. 33 As we know, the advanced functions and applications of nanostructures strongly depend on their chemical and physical properties, which are greatly inuenced by not only the crystal structures and chemical compositions but also the shape, size and dimensionality of the nanostructures. [22][23][24][25][26][27] Among them, nanostructured lanthanum hydroxides (La(OH) 3 ) have been widely applied in elds of catalyst, 28 superconductors, 29 optical coatings, 30 exhaust-gas convectors, 31 hydrogen storage materials 32 and high dielectric constant gate dielectrics.…”

Therefore, when rare earth hydroxides are prepared in the form of 1D nanostructures, they are proposed to be novel functionalized materials resulting from the unique shape and quantum connement effects.…”

Synthesis and Characterisation of Nano Lanthana

“…Various nano catalyst have been prepared previously among which ,rare earth compounds are interesting due to their fasinating catalytic [1],photonic, optoelectronic [2] and magnetic [3] properties, which originate from their 4f orbital electrons [4]. Lanthana (La 2 O 3 ) is a novel rare earth nano catalyst having many attractive applications in gas-exhaust converters [5], optical coatings [6], catalysts [7], super conductors [8], hydrogen storage materials [9] and next generation of high dielectric constant gate dielectrics [10].…”

3D bundles of self-assembled lanthanum hydroxide nanorods via a rapid microwave-assisted route

“…Lanthanum hydroxide (La(OH) 3 ) and oxide (La 2 O 3 ) are novel rare earth compounds which have been prepared so far with various nanoscale morphologies such as nanopowders [3,8], nanotubes [9], nanorods [10,11], nanowires [2] and nanobelts [12]. These materials have lots of applications in catalysts [10], superconductors [13], exhaust-gas convectors [14], hydrogen storage materials [15], optical coatings [16] and next generation high dielectric constant gate dielectrics [17].…”
