Abstract
Trigonal selenium nanoparticle is synthesized by precipitation method using three L-arginine concentrations and ascorbic acid and by varying aging time. In the XRD analysis, glassy nature of selenium is identified (pH ≈ 2.8) and turned into hexagonal structure at 2θ = 29.72° (pH = 7). Average size of the particle is 29–44 nm. The FTIR result is confirmed the presence of selenium at 464 cm−1 and one-dimensional (1D) structural changes are detected in the FESEM photographs. Energy gap is increased from 2.24–2.72 eV up to 24 h aging time and then decreased about 2.41 eV at 48 h.
