Monomer Emission and Excimer Emission of Pyrene Solution

Introduction

Fluorescence is the phenomenon observed when a substance transitions from the electronically excited state to the ground state. However, association may occur between excited-state molecules and ground-state molecules, thereby causing an emission (fluorescence). This state is referred to as an excited complex. If it comprises identical molecules, it is referred to as an excited dimer (excimer). If it comprises two different molecules, it is referred to as an exciplex. Examples of excimer usage include excimer lasers and measurement of intermolecular distances. This article introduces the measurement of monomer and excimer emissions of pyrene solution using the spectrofluorophotometer RF-6000.
