Technical Scope and Capabilities
This service provides luminescence-related measurement and analysis using complementary luminescence spectroscopy setups.
The service includes
- steady-state and quasi-steady-state photoluminescence measurements across the UV-VIS-NIR range
- evaluation of material optical quality, optical transitions and defect-related emission
- time-resolved luminescence measurements with nanosecond resolution
- luminescence decay kinetics and carrier lifetime evaluation
- temperature-dependent luminescence studies from 8 K to 300 K
- analysis of thermally activated processes, defect behaviour and exciton dynamics
- excitation-dependent luminescence studies
- recombination-dynamics analysis across excitation intensities
- high-resolution spectral measurements in the 160–850 nm range
- custom optical measurement configurations
- data analysis and scientific or technical consultation.

Target Audience and Possible Clients
The service is intended for
- semiconductor and optoelectronic companies characterising LEDs, lasers, detectors and thin-film materials
- high-tech manufacturers working with UV-VIS components, coatings or luminescence materials
- start-ups and SMEs developing photonic or nanomaterial-based technologies
- industrial R&D teams testing prototypes, material batches or device performance.
Possible Restrictions
Measurements cannot be performed independently by clients. Experiments must be carried out by trained staff. Throughput is limited because setup and calibration require additional time. Large batches must be scheduled in advance. Access may depend on existing research schedules. Custom configurations may require prior consultation.
