    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

    The LQ-100X-PL is the most compact photoluminescence (PL) and photoluminescence quantum yield (PLQY) test system —a NIST-traceable material analyzer with glovebox-compatible integration. 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.

    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.
