Template-free synthesis, characterization, growth mechanism and photoluminescence property of Eu(OH)3 and Eu2O3 nanospindles

Optical properties of biosynthesized nanoscaled Eu2O3 for red luminescence applications

“…Various physical and chemical processes are reported for the synthesis Eu2O3 NPs like sol gel, precipitation, ball milling, hydrothermal, thermal decomposition, pyrolysis, and hydrolysis [9][10][11][12][13][14][15][16]. Despite of being effective, these chemical and physical methods have their own pros and cons.…”

Hydrothermal Synthesis of Various Shape-Controlled Europium Hydroxides

“…The morphology of Eu 2 O 3 obtained by the calcination of Eu(OH) 3 submicrospindles maintains the same morphology as Eu(OH) 3 . The similar method of annealing the Eu(OH) 3 precursor to obtain Eu 2 O 3 with the same morphology as the former have been reported by others in succession in recent years [ 19 , 20 , 21 ]. Xu et al [ 22 ] obtained the monodisperse and well-defined 1D rare earth fluorides (β-NaREF 4 ) (RE = Y, Sm, Eu, Gd, Tb, Dy, and Ho) nanowires/nanorods using RE(OH) 3 as precursors via a facile hydrothermal route and characterized their photoluminescence properties.…”

Effects of mineralizing agent on the morphologies and photoluminescence properties of Eu3+-doped ZnO nanomaterials

“…Up to now, various techniques have been developed for controlling shape, size and structures of such nanomaterials [12][13][14][15][16][17][18][19]. Moreover, the spontaneous emission probability of rare-earth doping nanoparticles can be significantly modified by changing the particle size, shape and surrounding medium [20][21][22][23][24][25]. However, the investigation about the Eu-doped ZnO nanomaterials with different morphology, in particular, the effects of various mineralizing agents on their morphologies and photoluminescence properties are limited [26,27].…”
