1)런던 콜레라지도
1854년 8월 31일 영국 런던의 소호 지역에서 발생한 콜레라의 원인을 파악하기 위해 의사 존 스노는 런던 지도를 사용했다. 스노는 감염에 따른 사망자 수와 주소가 포함된 기초 데이터를 확보했
Phosphor (Energy Converter)
Inorganic phosphor materials
“Classical” inorganic phosphors usually consist of a host lattice with activator ions doped into it in small concentrations, typically a few mole percent or less.
Host lattice & Activator ion
1st type : weak interaction (Ln3+)
2nd type: strong interaction ( Mn2+, Eu2+, Ce3+, Pb2+,Sb3+, Ce3+, MoO42-, NbO43-)
Activator (+ Sensit
