Description
Pd1−xRux(0.1<x<0.6)
で表される。
本実施形態では、本発明の第1の実施形態に係る水素吸蔵体について説明する。
Pd1−xRux(0.1<x<0.6)・・・(1)
で表される化合物であることが好ましく、一般式
Pd1−xRux(0.15<x<0.55)・・・(2)
で表される化合物であることがより好ましい。
本実施形態では、本発明の第2の実施形態に係る水素吸蔵体について説明する。
本実施形態では、本発明の第3の実施形態に係るガスクロミック型調光素子について説明する。
本実施形態では、本発明の第4の実施形態に係る水素センサーについて説明する。
本発明の第5の実施形態に係る水素感知素子は、本発明の第3の実施形態に係るガスクロミック型調光素子と同様の構成であるため、説明を省略する。
本実施例では、基材40としての、ガラス基板上に、マグネシウム・イットリウム合金からなる水素吸蔵層10、タンタルからなる拡散防止層50、パラジウム−ルテニウム合金からなる触媒層20が順次積層されている、水素吸蔵体200を有するガスクロミック型調光素子400を作製した。
Mg0.4Y0.6
で表わされるマグネシウム・イットリウム合金薄膜(水素吸蔵層10)を成膜した。このとき、スパッタ中のアルゴンガス圧を0.3Paとし、直流スパッタ法により、それぞれのターゲットに所定時間印加することでスパッタした。
Pd1−xRux(x=0.1、0.2、0.3、0.4、0.5、0.6、0.7、0.8、0.9)
で表わされるパラジウム・ルテニウム合金薄膜(触媒層20)を成膜し、実施例1〜9の水素吸蔵体200を有するガスクロミック型調光素子400を作製した。
金属パラジウムのみに電力を印加して、x=0とした、即ち、パラジウム薄膜(触媒層20)を成膜した以外は、実施例1〜9と同様にして、水素吸蔵体200を有するガスクロミック型調光素子400を作製した。
以上の手順によって作製したガスクロミック型調光素子400は、金属光沢の反射状態になっていた。さらに、大気中で500時間放置しても、ガスクロミック型調光素子400は、同様に金属光沢の反射状態になっていた。パラジウム・ルテニウム合金薄膜の表面をアルゴンで4体積%に希釈した1気圧の水素ガス(以下、「水素含有ガス」という)に曝すと、マグネシウム・イットリウム合金薄膜が水素を吸蔵すること、即ち、水素化することにより、透明状態に変化した。この状態で、パラジウム・ルテニウム合金薄膜の表面を大気に曝すと、水素を放出すること、即ち、脱水素化することにより、反射状態に戻った。以上のように、常温・常圧における水素の吸蔵及び放出、即ち、水素化及び脱水素化により、ガスクロミック型調光素子400の光学特性は変化した。
ガスクロミック型調光素子400を大気中で500時間放置した後、ガスクロミック型調光素子400の光透過率を測定した。
0.1<x<0.6
を満たすとき、スイッチング時間が短いことがわかる。これは、ルテニウムと合金化することで、パラジウムの触媒作用が大気中に放置しても劣化しないためであると考えられる。
