Abstract: There is provided a photoreactor for the remediation of gaseous emissions and/or contaminated water using ultraviolet (UV) or vacuum ultraviolet (VUV). There is also provided an emission source for generating UV and/or VUV, the source comprising: a microwave generator; a chamber arranged to receive microwaves generated by the microwave generator, the chamber comprising: a gas comprising species for forming excimers; a resonator arranged to receive the microwaves in the chamber and generate a plasma; a first electrode spaced apart from the resonator; and a voltage source configured to generate an electric field between the resonator and the first electrode, wherein, on application of the electric field, the electric field drives electrons and/or ions from the plasma to generate excimers and produce vacuum ultraviolet or ultraviolet emission. There are also provided methods of generating UV and/or VUV, and methods of remediating fluids.
