Fig. 1 — Scanning electron micrographs of HoAcAc nanoparticles showing the effect of emulsifier on particle diameter and surface a particles prepared using PVA as emulsifier, b particles prepared using DMAB as emulsifier (stirrer speed was 24,000 rpm for both formulations), c particles prepared using DMAB as emulsifier after neutron irradiation (1 h at a neutron flux of 5 × 10¹² n cm⁻² s⁻¹). The magnification was 100,000x for all samples; bar represents 500 nm.
