Preparation and characterizations of tantalum pentoxide (Ta₂O₅) nanoparticles and UV‐curable Ta₂O₅‐acrylic nanocomposites

Tantalum pentoxide (Ta 2 O 5 ) nanoparticles with the sizes in the range of 20–50 nm were prepared via a chemical route in which the oleic acid (OLEA) was adopted as the surfactant for the synthesis process. X‐ray diffraction (XRD) revealed the as‐synthesized Ta 2 O 5 transforms from amorphous to hexagonal and orthorhombic structures at the temperatures of 700°C and 750°C, respectively, illustrating the suppression of recrystallization...
