A Rotating Sample Holder Using Flexible Fiber Optics for the Excitation and Detection of Photoluminescence at Liquid Helium Temperatures

Abstract

We describe a sample holder useful for the study of the angular dependence of photoluminescence at liquid helium temperatures. The system is characterized by a high collection efficiency and is particularly well suited to situations where there is only vertical access to the experimental space.

Fluorometric analysis

“…Flexible fiber optics have been applied with a rotating sample holder at liquid helium temperatures (978). A number of papers have been concerned with improving apparatus for the measurement of weak luminescence (197,254,478).…”
