Described are light generating devices employing ultraviolet (UV) light emitting diodes and one or more UV active materials, such as UV reflective materials, UV scattering materials, and UV transparent materials. A UV light generation system, may include a plurality of UV light emitting diodes arranged across a surface having a diffuse UV reflective layer. The UV light generation system may be arranged to enclose a fluid pathway or may be arranged as a liner of a container or vessel for use in disinfecting, purifying, or sterilizing fluid, particles or objects in the fluid pathway, container, or vessel by exposure of the fluid, particles or objects to UV light generated by the UV light emitting diodes.
