Grooved High-Reflective Films for Ultraviolet Emission Enhancement

Grooved High-Reflective Films for Ultraviolet Emission Enhancement

Conventional ultraviolet microplasma sources typically lack a back-reflection structure, resulting in radiative power loss from the backside. To enhance the emission efficiency of ultraviolet microplasma devices around 220 nm, we propose a multilayer reflective coating composed of alternating high-...
