実施例1
高真空下、TiO2層(100nm)、SiO層(100nm)及びTiO2層(100nm)をこの順序で昇華させてガラス板に付着させた。一方のサンプルを基準サンプルとして使用し(サンプル1)、他方のサンプル(サンプル2)を窒素雰囲気中550℃で2時間加熱した。
0.1Pa未満の真空下、SiOの昇華によってSiOyフレークを製造した。基材を事前にNaCl剥離層100nmでコーティングした。基材を脱イオン水で洗浄し、得られたフレークを脱イオン水で洗浄してNaClを除去し、乾燥させた。白く見える厚さ245nm±5%のSiOyフレークが得られた。SiOyフレークは、反射光で作動する顕微鏡の下では青く見えた。空気中の最大反射率の振幅は10%未満であった。
