Measures energy up to 7.0 eV.
AC-3
Features
・Capable of measuring up to 7.0 eV at atmospheric pressure
Incorporates special nitrogen substitution optical system capable of irradiating samples under atmospheric conditions with far ultraviolet light at energies of 6.2 eV or greater—something previously impossible due to atmospheric absorption.
Applications
・Ionization potential measurement of the following functional materials
Organic light-emitting diodes, organic solar cells, organic field-effect transistors, photoreceptor materials for photocopiers, Perovskite solar cells, quantum dots, carbon nanomaterials, catalyst materials, storage batteries, fuel cells, semiconductor materials (e.g., Si, GaN, GaAs)
