②White emission using mixtures of CdSe quantum dots and PMMA as a phosphor
This paper explain WLED that have mixture stucture (one single chip(emit blue light) and cdse/PMMA quantum dots). CdSe quantum dots are synthesized by the wet chemical method using CdO and Se powder as precursor. And they control the size of quantum dot and mix the phospors(PMMA).
These quantum dots have three differe
부르는 이름.
▶ Nanocrystal (NC): 잘 발달된 일정한 결정구조를 갖고 있는 나노물질.
▶ Quantum yield(QY) : 양자수,: 흡수한 빛에 대해 얼마만큼 일 (형광, 반응, 다른 state로의 전환등)을 해주었는가를 나타내는 것
§이paper에서는 Quantum Dot으로 높은 Quantum yield을 가진 CdSe/ZnS core/shell Nanocrystal사용한다
The lens is used to focus the sectioned UV light down to a smaller area on the chip. The smallest feature size capable of being written on the wafer is a function of the numerical aperture of the lens as well as the wavelength of the light.
uses a patterned elastomer(e.g. PDMS(Poly DiMethyl Siloxane)) as the stamp, mold, or mask to generate micro-patterns and microstructures
