| Research Abstract |
We investigated and clarified mechanisms of atomic emissions of suspended samples including metallic particles using non-equilibrium atmospheric-pressure plasma by systematically measuring spatial profiles of densities of electrons and metallic atoms, and gas temperatures and so on.
Main results are as follows. 1. Atomic emission is enhanced by atomic ions irradiation to the sample. 2. Atomic emission profiles correspond to the metallic atom densities. Especially, the density is highest near the sample electrode and rapidly decreases as the distance from the electrode increases. 3. Atomic emission intensity depends on the ratio of water included in the samples and the efficiency of atomic emission increases as the water ratio of samples decreases.
