Dye-sensitized Upconversion nanophosphors and methods of synthesizing the same

The present invention relates to a nano-phosphor comprising a core and a first shell surrounding at least a portion of the core, and to a dye-sensitized up-conversion nano-phosphor, which has an absorption band ranging from 650 to 850 nm by bonding an organic dye to a surface of the nano-phosphor, a...

Beschreibung
Zusammenfassung:	The present invention relates to a nano-phosphor comprising a core and a first shell surrounding at least a portion of the core, and to a dye-sensitized up-conversion nano-phosphor, which has an absorption band ranging from 650 to 850 nm by bonding an organic dye to a surface of the nano-phosphor, and is excited in a near infrared region and emits visible light. 본 발명은 코어와 상기 코어의 적어도 일부를 둘러싸는 제 1 쉘을 포함하는 나노형광체이며, 상기 나노형광체의 표면에 유기염료가 결합되어, 650 nm부터 850 nm 범위의 흡수 밴드를 가지며, 근적외선 영역에서 여기되어 가시광을 발광하는 염료감응 상향변환 나노형광체를 제공한다.
