Abstract

In the field of single-molecule spectroscopy, it is essential to analyze luminescence Intensity changes that result from a single molecule. With the CdSe/ZnS core-shell structured quantum dot photon emission data Bayesian multiple change-point estimation is done with the gamma prior for Poisson parameters and truncated Poisson distribution for the number of change-points.

단일 분자에서 발생한 발광의 세기 변화를 분석하는 문제는 단분자 분광학에서 반드시 필요하다. 본 연구에서는 카드뮴셀레나이드/황화아연의 중심-껍질 구조를 갖는 양자점에 대한 단분자 분광학 데이터에 대해 Poisson count data로서 베이지안 접근으로 모수에 대한 공액 감마분포와 변화점 개수에 대한 절단포아송 분포로 사전분포를 주고 다중변화점을 추정하였다.
