LuQY Lifetime
Time-Resolved Photoluminescence
LuQY Lifetime is a compact, fully integrated system for time-resolved photoluminescence and charge-carrier lifetime analysis in thin films, layer stacks and complete optoelectronic devices. High-sensitivity TCSPC detection resolves photoluminescence decay dynamics across a wide temporal range, while automated acquisition and analysis deliver characteristic lifetimes directly in the LuQY software.
Overview
About LuQY Lifetime
LuQY Lifetime is an integrated time-resolved photoluminescence system designed for the characterization of charge-carrier dynamics in semiconductor thin films, layer stacks and complete optoelectronic devices. It combines pulsed optical excitation, sensitive photon detection and automated decay analysis in a compact measurement platform.
Following optical excitation, the system records the temporal evolution of the photoluminescence signal using time-correlated single photon counting (TCSPC). The resulting decay profile provides direct insight into charge-carrier recombination dynamics and allows characteristic lifetimes to be extracted from the measured response.
Adjustable excitation repetition rates and acquisition settings allow the measurement to be quickly adapted to different decay timescales, from a few nanoseconds to several microseconds.
The LuQY software provides real-time visualization of photoluminescence decay curves, automated data storage and flexible further analysis. Measurement data and metadata can be stored in common database systems.
