Abstract
Description
1)電流・電圧の印加により可逆的に光透過率の変化するエレクトロクロミック材料
2)温度により光透過率が変化するサーモクロミック材料
3)雰囲気ガスの制御により光透過率が変化するガスクロミック材料
この中でも、調光素子として酸化タングステン薄膜等のエレクトロクロミック材料を用いたエレクトロクロミック調光部材の研究が最も進んでおり、現在、ほぼ実用化段階に達しており、市販品も出されている。しかしながら、エレクトロクロミック調光部材は十分な光学特性を得るためには調光部材を構成する調光素子を5層程度の多層薄膜構造にする必要があり、コストが非常に高くなってしまうという問題がある。これに対して、ガスクロミック調光部材は調光素子の構造がエレクトロクロミック調光部材に比べて簡単なので、低コストで製造できる調光部材として期待されており、その調光素子の材料や調光部の構造について各種検討がなされてきた(例えば、特許文献1~4)。
