    Area of Science:

    • Photonics
    • Optics
    • Materials Science

    Background:

    • Spectrum conversion films trap intrinsic photons, limiting light extraction efficiency.
    • Optimizing photon extraction is crucial for enhancing the performance of photonic devices.
    • Existing planar structures suffer from significant photon loss.

    Purpose of the Study:

    • To design and evaluate a micro-sized photonic structure for improved photon extraction from spectrum conversion films.
    • To accurately simulate the spectral performance and efficiency of micro-structured films.
    • To quantify the enhancement in external quantum efficiency (EQE) compared to planar films.

    Main Methods:

    • Utilized Monte Carlo ray-tracing simulations to model photon extraction.
    • Employed a mean free path concept for accurate spectral simulation of the film.
    • Calculated key performance metrics including external quantum efficiency and self-absorption efficiency.

    Main Results:

    • Achieved 89% extraction of trapped photons from the spectrum conversion film into free space.
    • Demonstrated a two-fold increase in total external quantum efficiency with micro-structures.
    • Observed a four-fold increase in forward-viewing external quantum efficiency compared to planar films.

    Conclusions:

    • Micro-sized photonic structures significantly enhance photon extraction efficiency in spectrum conversion films.
    • The proposed simulation method accurately predicts film performance, including EQE.
    • Micro-structuring offers a viable pathway to substantially improve the performance of photonic light management devices.
