ZnAl2O4 nanofibers and nanoparticles were in situ synthesized by electrospinning technique. Utilizing poly (vinyl pyrrolidone) (PVP) with different degree of polymerization, SEM (scanning electron microscope) results indicate that ZnAl2O4 nanostructures exhibit different morphologies under the same electrospun parameters. When PVP with high molecular weight (Mw = 1,300,000) was used, the ultra-long ZnAl2O4 nanofibers were obtained with an average diameter of ∼200 nm. However, while PVP with low molecular weight (K-30) was used, the ZnAl2O4 changed into particle-shape with an average size of ∼100 nm. Utilizing Nd3+ ions as the optical activator, three emission peaks centered at 905 nm, 1064 nm and 1335 nm were detected respectively in the photoluminescence (PL) spectra of ZnAl2O4:Nd3+ nanostructures under 808 nm laser excitation. It is noticed that both the excitation wavelength (808 nm) and the emission wavelength (905 nm and 1064 nm) are located in the 700–1100 nm optical window of cells and tissues. And the cytotoxicity investigation indicates ZnAl2O4:Nd3+ nanostructures are biocompatible with human cells, which endow their potential application as biological mark-ers, etc.
