Division of Optical Spectroscopy

The Optical Spectroscopy Division focuses on the development and investigation of modern luminescent materials with potential applications in optoelectronics, photonics, telecommunications, medicine, lighting, and document security.

The research involves the design and synthesis of novel chemical compounds, including nanomaterials, followed by the analysis of their optical, thermal, electrical, magnetic, and structural properties. Particular attention is given to understanding the mechanisms of light emission and exploring practical uses of the studied materials.

The head of the department is prof. dr hab. Przemysław Dereń

Research

Development of materials for energy-efficient light sources and advanced displays,
Design of bioactive composites for medical applications,
Creation of secure luminophores for markings and anti-counterfeiting measures,
Investigation of materials for optical data storage,
Photocatalytic hydrogen generation using light-based processes,
Studies on Stokes and anti-Stokes luminescence phenomena,
Emission analysis of nanomaterials in relation to their morphology and grain size,
Synthesis of “artificial molecules” – intentionally coupled quantum dot systems.

The Division also conducts research on laser-induced broadband white emission, scintillating materials, and high-energy radiation converters. These efforts aim to develop advanced materials for next-generation optical and electronic technologies.
