Beschreibung
Zusammenfassung:	The present invention relates to an upconversion nanophosphor in a core-multiple shell structure. In particular, the present invention provides: an upconversion nanophosphor which is excited by near-infrared rays of 00 ± 20 nm, 980 ± 20 nm, and 1,530 ± 20 nm wavelengths, and thus can display green, red, blue light, and various luminous colors consisting of combinations thereof; and a transparent polymer composite comprising the upconversion nanophosphor. 본 발명은 코어-다중쉘 구조의 상향변환 나노형광체로 800 ± 20 nm, 980 ± 20 nm, 1530 ± 20 nm 파장의 근적외선에 의해 여기되어 녹색, 적색, 청색 발광 및 이들의 조합으로 이루어진 다양한 발광색을 나타낼 수 있는 상향변환 나노형광체 및 이를 포함하는 투명 고분자 복합체를 제공한다.
