Description
面に向けて移動する過程と、そして該蒸発粒子が基板に付着して薄膜を形成する過程とからなるが、本発明の製造方法は、これらの過程のうち、蒸発粒子となった誘電体材料が基板に付着して薄膜を形成する過程において、水素イオンを誘電体材料に作用させる。そして、このように水素イオンを誘電体材料に作用させるために、アシストエネルギーの基板への直接印加が必要となるのである。アシストエネルギーの直接印加は例えば、イオンビームを基板に直接に照射することや、基板に直接に高周波電力を印加することにより達成できる。
る。
高屈折率材料であるTiO2をガラス基板上に真空蒸着法により成膜し、誘電体光学薄膜を製造した。該製造は、雰囲気の圧力を2×10-2Paに、また基板の温度を200℃に保持しながら、1500Wの高周波電力を基板に直接印加して、酸素ガスと水素ガスとを含んで成る混合ガス雰囲気中で行った。混合ガス雰囲気中に存在する水素ガスの量は、水素ガスと酸素ガスとの合計量に基いて0.1%、0.5%、1.0%、2.0%に変化させた(実施例1〜4)。また比較の目的で、水素ガスの量が0%、3.0%、4.0%である場合についても、誘電体光学薄膜の製造を行った(比較例1〜3)。
製造した各誘電体光学薄膜を有するガラス基板について、その屈折率および透過性を以下のように評価した。
屈折率:波長550nmの光についての屈折率を測定した。
透過性:波長400nmの光がガラス基板を通過する際に吸収された光量を測定し、これを吸収率として百分率で示した。吸収率が低ければ低い程、透過性は高いことを示す。
実施例1では、混合ガス雰囲気中に水素ガスを0.1%添加したため、屈折率は約2.45の高い値となり、また吸収率は約1%の低い値となって良好な透過性を示した。
実施例2では、混合ガス雰囲気中の水素ガスの量を実施例1より多い0.5%にしたところ、約2.45の屈折率を保ったまま吸収率が約0.7%に減少してより良好な透過性を示した。
実施例3では、混合ガス雰囲気中の水素ガスの量をさらに増加させ1.0%とし、その結果、屈折率は約2.45のままであるにも関わらず、吸収率がさらに0.5%に減少し良好な透過性を示した。
実施例4では、混合ガス雰囲気中の水素ガスの量を2.0%に増加させたが、得られた結果は屈折率および透過性共に実施例3のものと同一であり優れたものであった。
一方、比較例1では、混合ガス雰囲気中に水素ガスを全く添加しなかったため、屈折率は2.45と高かったものの、吸収率が3.0%と大きく透過性が良好でなかった。
また、比較例2では、水素ガスの量を増加させて3.0%にしたところ、透過性は実施例3および4のものと同様に良好であったが、屈折率が2.3に低下した。
さらに、比較例3では、混合ガス雰囲気中に4.0%の多量の水素ガスを添加したため、透過性は実施例3〜5と同程度であったが、薄膜の充填密度が減少して屈折率が約1.8へと大幅に低下した。
図2(a)に図示される実施例2の誘電体光学薄膜からの回折図には有意な回折ピークが存在しなかった。これは薄膜中に実質的に結晶構造が存在せず、アモルファス構造にあることを示す。
それに対して、図2(b)に図示される比較例1の誘電体光学薄膜からの回折図には、2θが約26°、約39°、約48°、約54°等の位置で明らかな回折ピークが存在した。これらの回折ピークは薄膜が結晶構造にあることの証拠である。
これらの結果より、本発明に従って製造された誘電体光学薄膜では、製造の際の混合ガス雰囲気中に含まれる水素ガスに由来する水素イオンの作用によって結晶成長が阻害され、アモルファス構造にあることが解る。
