Fig. 4From: Preliminary Studies on Biodegradable Zinc Oxide Nanoparticles Doped with Fe as a Potential Form of Iron Delivery to the Living OrganismCathodoluminescence (CL) spectrum of ZnO:Fe NPs. Dry nanopowder was pelletized to obtain CL spectrum originating from large volume of the sample. Shown bands illustrate quantity and quality of crystallographic defects present in zinc oxide nanocrystalsBack to article page
