Description
図1は、本発明の実施形態1に係る電場増強基板を用いた発光増強基板1を示す。この発光増強基板1は、クリスタルバイオレットなどの発光体の発光を増強するために用いられる基板である。本実施形態において発光体とは、外部からの刺激により、当該発光体を構成する分子、原子又はイオン等の電子状態が基底状態から励起状態に励起された後、再び基底状態に遷移する際に、基底状態と励起状態とのエネルギーの差分を光として外部に照射するものをいう。発光体からの発光としては、所定波長の光に発光体が励起されることによる発光(フォトルミネセンス)に限らず、例えば、電場印加により発光体が励起されることによる発光(エルクトロルミネセンス)や、化学反応により発光体が励起されることによる発光(ケミルミネセンス)等であってもよい。
図2は、本実施形態2に係る電場増強基板を用いた発光増強基板101を示す。本実施形態2に係る発光増強基板101は、基板102が酸化チタン粒子層104と一体形成されている点で上記実施形態1とは異なる。
本実施例1では、ガラス基板上に酸化チタンナノ粒子体からなる酸化チタン粒子層を形成することで製造した電場増強基板において、発光体の発光強度の増強度を検討した。
本実施例2では、酸化チタンナノ粒子体からなる粉末をペレット状に圧縮成型した電場増強基板において、発光体の発光強度の増強度を検討した。
