Optical properties of neodymium oxides at the nanometer scale

Optimization of the synthesis of nanostructured Tb3+-doped Gd2O3 by in-situ luminescence following up

“…This result was unexpected because precipitation using the polyol method was only observed at high temperatures regardless the type of the materials elaborated, sulfides [26], elemental metals [22,23] or oxides [27]. In particular, these lanthanide oxides were only prepared between 140 and 180 • C until now [28,30]. The size distribution obtained by PCS and a TEM image of the so-formed Gd 2 O 3 :Tb 3+ particles are shown in Fig.…”

“…the polyol method, has been widely and successfully used to synthesize a large variety of materials [21][22][23][24][25][26][27]. In our previous works [28][29][30], different lanthanide oxides (Gd 2 O 3 , Eu 2 O 3 , and Y 2 O 3 ) doped with different lanthanide ions (Tb 3+ , Eu 3+ , Nd 3+ ) have been prepared using this method. In these preparations, the mixed solution of precursors (chloride or nitrate of host and doping lanthanides) were heated and stirred at 140 • C until the complete dissolution of the components and aqueous NaOH was then added to form the oxide of lanthanide.…”

Syntheses of Nd2O3 nanowires through sol–gel process assisted with porous anodic aluminum oxide (AAO) template

“…been investigated thoroughly [11][12]. Many methods have been successfully applied for the preparation of neodymium oxide nanoscale materials [13][14][15][16][17].…”

Nd2O3: Eu3+nanocrystalline phosphor–a new potential thermoluminescing material for dosimetry

“…Soliman [3] has reported that commercial Nd 2 O 3 is an efficient gamma-ray dosimeter. To the best of our knowledge, there have been only a few reports [4,5] An aqueous solution containing stoichiometric amounts of analar grade neodymium nitrite, europium nitrate and ODH was contained in a petri dish of approximately 300 mL capacity. The excess water was allowed to evaporate during heating over a hot plate until a wet powder was left.…”
