Abstract
Description
material)とを含み、波長変換層は、発光表面に取り付けられた厚さが5〜20ミクロンである。

toughening additive)が、波長変換層に適用することができ、特に膜の薄化の結果としての波長変換層へのクラッキング又は損傷を低減し得る。本明細書に開示される実施形態による波長変換層は、セリウムを含まず、1つ以上の光の特性を変換するように構成された材料を含んでもよい。波長変換層は、光の波長、位相等のような光の特性を変換することができるが、これらに限定されない。波長変換層は、波長変換層内の1つ以上の粒子による入射光の吸収に基づいて、光の特性を変換し、その後、光子を放出することができる。波長変換層は、希土類イオンからの活性化を有し又は有しない蛍光体粒子などの、適用可能なルミネッセンス粒子又は光学的散乱性粒子(optically scattering particles)を含んでもよい。
recombination rate)を低下させる可能性がある。非放射再結合は、電荷キャリアが光子を放出することなく再結合するプロセスである。非放射性再結合は、熱や振動のような意図しない副産物を生成する可能性がある。特に、非放射性再結合は、伝導帯内又は局所的アクティベーター励起状態内の電子が、価電子帯内の正孔又は局所的アクティベーター基底状態内の正孔と再結合し、過剰のエネルギーが放出されるときに、起こる。非放射再結合は、閾値電流を増加させ、画素の性能及び/又は効率を低下させる可能性がある。
