Abstract

A mnode-locked laser was used to measure fluorescence decay down to 80 picoseconds. Measurements on the fluorescence of methylene blue quenchled with potassium iodide demonstrate the effectiveness of the method. Fluorescence decay times of chlorophyll b (3.87 +/- 0.05 nianoseconds) and c-phycocyanin (1.14 +/- 0.01 nanoseconds) in vitro and chlorophyll a in the green alga Chlorella pyrenoidosa (1.14 to 1.6 nanoseconds) compare well with some of the existing data.

摘要

使用锁模激光器测量低至80皮秒的荧光衰减。对用碘化钾猝灭的亚甲蓝荧光进行的测量证明了该方法的有效性。体外叶绿素b(3.87±0.05纳秒)和藻蓝蛋白c(1.14±0.01纳秒)以及绿藻小球藻中叶绿素a(1.14至1.6纳秒)的荧光衰减时间与一些现有数据相当吻合。
