The ZnO MW UV dosimeter response with the presence of visible light emitted from interior fluorescent lamps (37 μm/cm²). (a) The relationship between photocurrent and UV accumulation compared with the reference plot. The inset shows the time-resolved photocurrent changes. (b) Relative error of the deduced UV accumulation.
