CTAB assisted sol-gel synthesis and characterization of FeWO ₄ and CoWO ₄ nanoparticles

Investigation of electronic structure, morphological features, optical, colorimetric, and supercapacitor electrode properties of CoWO4 crystals

“…Moreover, these CoWO 4 crystals exhibit irregular sphere-shaped with major percentual for average crystals size at around 31% referent to 275 nm. Therefore, according to the literature [119], these CoWO 4 crystals are not nanometric, since the nanocrystals present an average size distribution from 1 to 100 nm, when belonging to nanoscale, with significant and intriguing optical properties [120]. Moreover, the average particle size distribution of CoWO 4 crystals obtained by the PP method has been estimated in the range from 600 nm to 1.5 lm (Fig.…”
