Gas-phase chemiluminescence of reactive negative ions evolved through corona discharge in air and O2 atmospheres†
Abstract
The reactive performance of negative ions evolved in air and O2 atmospheres through a gas-phase chemiluminescence (CL) method was investigated, and was attributed to the reaction between negative oxygen ions (O2−) to evolve emissive singlet oxygen (1O2) species, and a novel CL system was established.
