Synthesis and characterization of nickel selenide nanoparticles: size and shape determining parameters

Structural, magnetic, and optical properties of nano‐sized Ni0.85Se

“…Each peak corresponds to an energy level manifesting the discreet nature of electron energy levels in the nanoparticles. The wavelength of the excitonic peaks is a function of the composition and size of the nanoparticles . Smaller particles result in an excitonic peak at shorter wavelengths.…”

Probing the stoichiometry dependent catalytic activity of nickel selenide counter electrodes in the redox reaction of iodide/triiodide electrolyte in dye sensitized solar cells

“…The colloidal method has been shown to be effective at controlling the growth and morphology of the nanoparticles and this characterized by quick nucleation, followed by the growth of the nuclei driven mostly by monomer concentration and temperature. 11,12 The colloidal method has two routes of syntheses, one that involves the injection of precursors in a hot solvent and the other that involves quick heating up of precursors in a high boiling solvent from room temperature to the desired temperature and this route is better known as the non-injection synthesis (NIS). There is however scarce information on the NIS of Ni x Se y systems.…”

Limiting the Oxidation of WS2 Nanostructures by Oleylamine Surface Passivation for Room Temperature NH3 Sensing

“…Of the various synthetic methods employed to fabricate WS2 nanostructures, the colloidal method provides a platform for tuning the morphology, electrical and optical properties of the nanostructures. This is achieved by merely varying reaction conditions such as the choice of precursors, concentration, capping agents, time and temperature [8][9][10]. Different morphologies of WS2 nanostructures such as nanorods, nanoflakes, nanoflowers and nanosheets have been fabricated through these synthetic methods for application in gas sensing.…”
