At QYB, we develop compact scientific instruments for absolute luminescence quantum yield (LuQY) characterization of semiconductor materials and devices. Our tools combine calibrated measurements of PLQY, ELQY, QFLS, spatial uniformity and time-resolved photoluminescence. As former academics, we understand that absolute luminescence measurements should be precise and straightforward, and so should turning them into reliable, meaningful insights. Accordingly, our instruments adapt to your sample's needs, offering one-click, hands-off control of a dynamic range of photoexcitation intensities and bias measurement conditions. In seconds, our software turns these calibrated measurements into quantitative results oriented to understanding your end-device.Your sample should be the complicated part. Not the measurement.

Absolute luminescence measurements should be precise, controlled and straightforward. So should turning them into reliable, quantitative insights. As former academics, we understand both sides of the problem. QYB makes this practical through precisely calibrated systems that adapt to different measurement needs and integrate naturally into laboratory workflows. Compact LuQY instruments combine absolute calibration, device-oriented measurement conditions, flexible sample handling and integrated software for fast, reproducible results.
