“…They reported the crystallite size of the particles in the range of 30-35 nm. Sreeja and Joy (2007) prepared iron oxide nanoparticles using iron (II) chloride and iron (II) sulfate and the resulting crystals were found in the range 8-13 nm with an average particle size of 10 nm. Further, Katsuki and Komarneni (2001) studied the effects of temperature on the synthesis of Fe 2 O 3 nanoparticles.…”

We have tested modified hydrolysis method for the preparation of a-Fe 2 O 3 nanoparticles. The particles after synthesis were applied for a series of physicochemical techniques. Iron chloride was used as a precursor material. The particle size distribution was determined using zeta sizer and scanning electron microscopy. The surface area and the morphology of the particles vary by changing the concentration of the precursor material. The size of nanoparticles varies from 10 to 90 nm. The particles having size of 23 ± 1 nm were separated out from the solution and their size remains almost the same even after one month. Energy dispersive X-ray analysis (EDX) of Fe 2 O 3 nanoparticles confirms the purity of the desired material. The weight loss of the particles with respect to the temperature was studied by thermogravimetric and differential thermogravimetric (TG/DTG) analysis. X-ray diffraction (XRD) has been employed to study the crystallinity of the particles.

“…It is important to note that the agglomeration of nanoparticles is easily formed during the drying process. This problem has already been described by several authors (Reddy et al, 2007;Ramirez & Landfester, 2003;Sreeja & Joy, 2007). In this case, the grafting of polymers is performed on particle clusters instead of nanoparticles.…”

“…The average crystallite size was approximately estimated by Scherrer's equation using the full width at half maximum (FWHM) of the most intense peak (1 1 2). As reported in the literature [13], Scherrer's equation (Eq. (1)) is described as follows:…”

Abstract:SrMoO 4 :Eu 3+ red phosphors were prepared by combining sol-gel and solid-state route. Citric acid and ethylenediaminetetraacetic acid (EDTA), employed as the chelating agents, were added to the aqueous solutions of metal nitrates. X-ray diffraction (XRD) and photoluminescent spectra techniques (PL) were used to characterize the resultant powders. The results indicated the obtained SrMoO 4 :Eu 3+ phosphors were fine powders with a particle size of 50 nm. The effects of synthesizing conditions were also investigated and optimized, which included the synthesis temperature and the activator concentration on the luminescent intensity. Compared with SrMoO 4 :Eu 3+ phosphors prepared by Solid-state reaction SrMoO 4 :Eu 3+ phosphors prepared by combining sol-gel and solid-state route showed appropriate particle size and a higher emission intensity.
