Methods, systems, and devices for inactivating microorganisms are disclosed. An example light emitting device that inactivates microorganisms on a surface comprises a light emitter configured to emit a first light comprising a first wavelength in a range of 380 nanometers (nm) to 420 nm, a first light-converting material configured to convert a first portion of the first light to at least a second light comprising a second wavelength different from the first wavelength, and a second light-converting material configured to convert a second portion of the first light to at least a third light comprising a third wavelength different from the first wavelength, wherein at least the first light, the second light, and the third light mix to form a disinfecting white light.
