What Does PLE Stand For?

PLE stands for Photoluminescence Excitation

Photoluminescence Excitation (PLE) refers to a spectroscopic technique used to investigate the electronic properties of materials by measuring the luminescence emitted as a result of excitation with specific wavelengths of light. This method allows researchers to analyze energy levels, identify electronic states, and understand various optical phenomena in semiconductors, nanomaterials, and other complex systems. PLE is instrumental in material characterization and can provide insights into exciton dynamics, defect states, and band structure.
