UV 방사선에 노출된 때 밝은 상태에서 어두운 상태로 그리고 전압의 인가시 어두운 상태에서 밝은 상태로 전환가능한 가변 투과율 광 필터가 제공된다. 본 광 필터는 일렉트로크로믹 및 포토크로믹 특성을 가진 하나 이상의 발색단을 포함하는 스위칭 재료를 포함한다. Variable transmittance optical filters capable of transitioning from a light state to a dark state on exposure to UV radiation and from a dark state to a light state with application of an electric voltage are provided. The optical filters comprise a switching material that comprises one or more chromophores that have electrochromic and photochromic properties.
