    Area of Science:

    • Materials Science
    • Optical Engineering
    • Computational Chemistry

    Background:

    • Perovskites are promising for optical fiber sensing coatings, but material discovery is limited and costly.
    • High trial-and-error costs hinder the use of diverse perovskites in optical sensing.
    • Current applications utilize only a few perovskite materials for optical sensing.

    Purpose of the Study:

    • To establish a systematic computational screening strategy for discovering novel perovskite coating materials.
    • To accelerate the identification of perovskite optical fiber performance enhancers (POPEs) for improved optical sensing sensitivity.
    • To overcome the limitations of traditional material discovery methods in optical fiber sensing.

    Main Methods:

    • A novel computational screening strategy was developed and validated.
    • 10 sampling methods and 10 classification algorithms were compared for optimal prediction.
    • The SMOTE-ENN sampling method combined with label spreading (LS) algorithms achieved 100% accuracy in cross-validation.
    • 500 perovskite material samples were analyzed using the optimal model.

    Main Results:

    • The developed screening strategy effectively accelerates the discovery of perovskite optical fiber performance enhancers (POPEs).
    • The optimal model (SMOTE-ENN + LS) demonstrated 100% accuracy and precision in leave-one-out cross-validation.
    • 237 novel potential POPEs were identified for the first time from 500 screened perovskite materials.
    • High formation probabilities (>91%) were predicted for common fluorescence sensing perovskites, validating the strategy.

    Conclusions:

    • The systematic computational screening strategy is effective for identifying novel perovskite materials for optical fiber sensing.
    • The identified 237 POPEs represent a significant advancement for next-generation fiber optic sensing technologies.
    • Further experimental validation and numerical simulations are recommended to confirm the predicted performance of these POPEs.
