Abstract :
ZnO nanocrystallites of average size 20 nm, agglomerated into ~300nm irregular nanoparticles, were prepared by a hydrothermal method. Laser excitation yielded brilliant second-harmonic generation which was imaged with mum resolution, suggesting good potential for biomedical applications.
