So, we selected SK energy Company. In the light of financial, we analyzed this company with some tools. Although it is hard to handle all kind of method and even specific numbers, we tried to find what the company has done. The or
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
