Beschreibung

Efficient luminescent materials emitting in the near-infrared (NIR) spectral range (800–2500 nm) are becoming increasingly important in modern technology. NIR light plays a key role in optical sensing, telecommunications, night vision, machine vision, biomedical diagnostics, security systems, and energy-related applications. Compared to visible light, NIR radiation offers deeper penetration into materials, reduced scattering, and lower sensitivity to ambient lighting conditions.
Despite their importance, the number of efficient and stable NIR luminescent materials is still limited. Many existing materials suffer from low efficiency, poor thermal stability, or complex and expensive synthesis routes. Therefore, exploring new classes of NIR phosphors is a highly relevant topic in materials science with strong technological impact.
The main goal of this Master’s project is to synthesize a new class of NIR phosphor materials using high-temperature solid-state reactions. After synthesis, the student will carry out a comprehensive characterization of the materials, covering both structural and optical properties.
The structure and morphology of the synthesized materials will be investigated using: X-ray diffraction (XRD) to identify crystal structure and phase purity; and scanning electron microscopy (SEM) to study particle size and morphology. These techniques provide insight into how synthesis conditions influence material structure.
The optical performance of the new phosphors will be studied using: Optical absorption measurements; Photoluminescence spectroscopy in the NIR range; Photoluminescence quantum yield measurements: and Luminescence lifetime analysis
This will allow the student to evaluate efficiency, emission mechanisms, and energy transfer processes in the materials.
This Master’s project is ideal for students who are interested in advanced materials with real technological relevance and who want to gain hands-on experience in both synthesis and characterization. The project provides a solid foundation for careers in materials development, optics, and sensor technology, as well as preparation for PhD-level research.
