    LQ-100X-PL: Photoluminescence and Luminescence Quantum Yield Test System.

    The LQ-100X-PL is the most compact photoluminescence and luminescence quantum yield test system compatible with powder, solution, and thin-film samples, and can be integrated into a glovebox. Using advanced instrument control software, in-situ time-resolved PL spectral analysis can be performed with simultaneous 2D and 3D graph generation, enabling faster and more efficient material characterization. For high-excitation studies, the LQ-100X-PL also provides 10-sun-equivalent high-intensity laser illumination with a 3 mm spot, enabling accurate PLQY and quasi-Fermi level splitting (QFLS) analysis under realistic operating conditions.

    Overview

    LQ-100X-PL evaluates Photoluminescence Quantum Yield(PLQY) of luminescent materials by measuring the number of photons emitted and the number of photons absorbed. It can be integrated with glovebox. It is compatible with powder, solution and thin film samples.

    Key Features

    • NIST-traceable, compact system with dimensions 502.4 mm × 322.5 mm × 352 mm, equipped with a 4-inch outer diameter PTFE integrating sphere and glovebox integration capability.
    • Advanced instrument control software enables in-situ time-resolved PL spectral analysis with simultaneous 2D and 3D graph generation, allowing users to complete material characterization more quickly.”
    • Outstanding optical design expands the spectral wavelength range, supporting extension up to 1700 nm. The LQ-100X-PL is compatible with powder, solution, and thin-film samples.
    • High-intensity laser system capable of achieving over 10 suns equivalent illumination with a 3mm spot.
