Preparation of Y2O3 nanoparticulate thin films using an emulsion liquid membrane system

Preparation of Sr2CeO4:Eu3+,Dy3+ White Luminescence Phosphor Particles and Thin Films by Using an Emulsion Liquid Membrane System

“…4 The particles a-c showed white luminescence, and the emission 19,20 The preparation of metal oxide particulate thin films with the ELM system, via casting the W/O emulsion containing precursor oxalate particles on the substrate followed by calcination, was achieved previously for Y 2 O 3 nanoparticles. 9 It was revealed that the carboxylic acid extractant such as VA-10 should be employed, since phosphorus was incorporated in the resulting metal oxide thin film when the phosphoric acid extractant such as D2EHPA was employed. In the present study, the W/O emulsion containing Sr and Ce oxalates was used as a soaking solution for the alumina substrate.…”

“…Preparation of Phosphor Thin Films. Only two previous reports on the preparation and characterization of the Sr 2 CeO 4 thin film, based on the pulsed laser deposition technique, have been published. , The preparation of metal oxide particulate thin films with the ELM system, via casting the W/O emulsion containing precursor oxalate particles on the substrate followed by calcination, was achieved previously for Y 2 O 3 nanoparticles …”

“…The oxalate particles prepared in the ELM system were then calcined to obtain both blue luminescent material, Sr 2 CeO 4 , and white luminescent material, Sr 2 CeO 4 :Eu 3+ ,Dy 3+ , and their size, morphology, and luminescence properties were investigated. The Sr 2 CeO 4 and Sr 2 CeO 4 :Eu 3+ ,Dy 3+ thin films were also prepared on alumina substrates by using the W/O emulsion containing the precursor oxalate particles as a soaking solution, according to the procedure previously employed for the preparation of Y 2 O 3 nanoparticulate thin films …”

In vitro antioxidant and antibacterial potential of biosynthesized yttrium oxide nanoparticles using floral extract of Illicium verum

“…When it comes to optoelectronics and chemical catalysis, it is one of the most exciting new elements on the horizon. Y 2 O 3 powder has a high dielectric constant and is very stable at high temperatures [6]. The great efficiency of Y 2 O 3 as an additive can be put to use in functional composite materials such as yttria-stabilized zirconia films.…”

Formation Mechanism of Zinc Oxalate Particles in the Internal Aqueous Droplets of Emulsion Liquid Membrane

“…[1][2][3][4][5][6] This typical process inspires researchers to employ ELM as reaction media for particle synthesis, i.e., employ the internal water droplets as micro reactors. Such facile and mild method has already been utilized to prepare various materials such as oxalate, [7][8][9] oxide, [10][11][12] cadmium sulfide, [13] phosphate, [14,15] calcium carbonate, [16,17] sulfate [14] and composites. [18][19][20][21] Morphology and size of the particles could be controlled through changing carrier concentration or water-oil ratio for controlling mass transfer rate.…”
