در اين مقاله نانو ذرات آهن وانادات با روش اولتراسونيك با استفاده از پيش ماده هاي NH4VO3و Fe(NO3)3.9H2O و بدون نياز به عامل پوشاننده، سورفكتانت و تمپليت سنتز شد. براي بررسي كاربرد نانوذره سنتز شده در سلول خورشيدي حساس به رنگ، سلول FTO/TiO2/FeVO4/Pt-FTO طراحي شد. آناليز VSM، مغناطش اشباع را emu/g 0.16 تعيين كرد. نانوذرات سنتز شده توسط پراش اشعه X ، ميكروسكوپ الكتروني روبشي، اسپكتروسكوپي مادون قرمز، آناليز VSMو EDS شناسايي شد.

This research reports a facile ultrasonic approach for the synthesis of iron vanadate (FeVO4 ) nanoparticles with the aid of ammonium metavanadate (NH4 VO3 ) and Fe(NO3 ) 3 .9H2 O as the starting reagents without adding external surfactant, capping agent or template in an aqueous solution. Furthermore, to examine the solar cell application of as-synthesized iron vanadate (FeVO4 ) nanoparticles, FTO/TiO2 /FeVO4 /Pt-FTO structure was created by deposited iron vanadate film on top of the TiO2 layer. The VSM magnetic measurement result shows that a maximum magnetization of 0.16 emu/g was obtained for FeVO4 nanoparticles after annealing at 550 ° C for 150 min. The as- synthesized FeVO4 ferrite powders were characterized by X-ray diffraction, scanning Electron Microscopy, spectra energy dispersive analysis of X-ray, and vibrating sample magnetometer techniques. The X-ray diffraction study showed that pure anorthic phase of FeVO4 nanoparticles have been produced after calcinations at 550 ° C for 150 min. Solar cell result indicates that an inexpensive solar cell could be developed by synthesis of FeVO4 nanoparticles through the ultrasonic approach.
