Conditional Optimization of Solution Combustion Synthesis for Pioneered La<sub>2</sub>O<sub>3</sub> Nanostructures to Application as Future CMOS and NVMS Generations

Abstract

The Present Research paper discuses the synthesis and characterization of lanthanum oxide (La 2 O 3) nanoparticles by using a very low cost Solution Combustion Method. We are using Acetamide as fuel in present method. In future, most of manufacturer of integrated circuits recently announced and introduced hafnium and lanthanum based high-κ dielectrics materials in their next CMOS generations and also Lanthanum oxides show some important applications such as luminescent devices, sensors, up-conversion materials, and catalytic fields. Now a day's researches are focuses on "higher-κ" materials with a dielectric constant of above 30 in order to satisfy the demands for future CMOS applications. FTIR spectroscopy was done for observing the presence of La-O bond. The synthesized lanthanum oxide nanoparticles were characterized by X-ray diffraction (XRD), Scanning Electron Microscopy (SEM) with EDAX spectra and Transmission Electron Microscopy (TEM) for morphological, percentage of metal and particle size determination. In XRD analysis, the average particle size was shown near 42 nm. Thermals analysis was done by TGA-DSC analyzer.

Zn/La Mixed Oxides Prepared by Coprecipitation: Synthesis, Characterization and Photocatalytic Studies

“…The spectrum of the initial sample Zn4La shows a sharp band from 3604 cm −1 attributed to the OH groups from the La(OH) 3 . The wide band centered at about 3450 cm −1 is assigned to the water molecules incorporated in the solid (ν H2O ) and coexists with the deformation band (δ H2O ) from 1567 cm −1 which disappears by heating/annealing at 400 • C. The bands located at 1485 cm −1 , 855,662 cm −1 correspond to the formation of La 2 O 3 mixed with LaO (OH) [35,36]. This is supported also by the disappearance of the band from 1019 cm −1 , the modification of the bands from 1417 and 695 cm −1 , which become less intense and suffer modifications of the aspect.…”

Techno-Economic Analysis of Lanthanum Oxide Nanoparticles Production using Combustion Solution and Hydrothermal Supercritical Water Condition

“…La2O3 material is produced by adopting the SC method suggested by Pathan, et al [10] and the HSWC method suggested by Hojo, et al [22].…”

“…Because of the high-quality applications of La2O3 nanoparticles in many fields, it was successfully fabricated using various chemical and physical methods. Several studies have reported on the synthesis of La2O3 by various methods, including combustion, coprecipitation, hydrothermal, sol-gel, reflux, sonochemical, solvothermal, spray pyrolysis, and thermal decomposition methods [9][10][11][12][13][14][15][16][17]. The method election for the production of lanthanum nanoparticles is based on advantages.…”
