Abstract
We demonstrate a technique for the deposition of nanometric Zn dots by phot odissociation of gas-phase diethylzinc using an optical near field under no nresonant conditions. The observed deposited Zn dot was less than 50 nm in size. The photodissociation mechanisms are based on the unique properties o f optical near fields, i.e., enhanced two-photon absorption, induced near-f ield transition, and a direct excitation of the vibration-dissociation mode of diethylzinc.
