Nano-sized crystals of neptunium dioxide (NpO2) were prepared successfully based on novel synthetic approach to neutralise a basic Np(IV) carbonate solution. The formation of nanocrystalline NpO2 was monitored by UV/visible absorption and X-ray absorption spectroscopies, and the resultant NpO2 crystals were further characterised by transmission electron microscopy.
