Photoluminescence spectroscopy is a non-contact, non-destructive optical characterization technique based on the analysis of light emitted by a material after light absorption (fluorescence or phosphorescence). It plays a crucial role in important studying the optoelectronic properties of semiconductors, quantum quantum dots, two-dimensional materials, and other nanostructures. The PL method is widely used in nanotechnology for bandgap measurement, defect analysis, and determination of energy le
