Beyond Empirical Fitting: A Physics-Grounded Approach
Traditional multi-exponential fitting for luminescence decay curves lacks physical meaning and fails to capture complex non-linear interactions. This research pioneers a hybrid framework combining metaheuristic optimization (Genetic Algorithm, Particle Swarm Optimization) with Runge-Kutta simulations, complemented by Physics-Informed Neural Networks (PINNs). This integrated approach accurately solves non-linear rate equations, providing a robust, physically grounded analysis of energy transfer dynamics.
Dominant Energy Transfer Pathway Identified
The study reveals that donor-acceptor energy transfer (N·kDA) is the dominant relaxation pathway in Eu²⁺-activated multi-site phosphors, significantly outweighing radiative (kr) and same-species interactions (N·kAA, N·kDD). Specifically, the non-radiative quenching rate (kn) and donor-acceptor transfer rate are found to be much faster than the radiative rate, highlighting the critical importance of activator concentration and defect control in phosphor synthesis.
AI for End-to-End Parameter Learning
Physics-Informed Neural Networks (PINNs) offer a unified, end-to-end learning framework that simultaneously determines solution trajectories and unknown rate constants. A key advantage is PINNs' ability to deliver consistent rate-constant evaluations even with drastically reduced experimental datasets. This approach leverages analytical differentiability and GPU parallelization for significant computational speedups, making complex analyses tractable and scalable for enterprise R&D.
kn ≈ N·kDA
Non-radiative quenching rate is similar to the donor-acceptor energy transfer rate, and both are significantly greater than the radiative rate.

Case Study: Accelerating Phosphor Discovery
A leading display technology firm struggled with slow and empirical phosphor development cycles. Traditional methods provided limited insight into the complex energy transfer mechanisms in novel multi-site phosphors, leading to costly trial-and-error iterations. By implementing an AI-enhanced rate equation modeling platform, the firm was able to precisely characterize the optimal activator concentrations and identify critical non-radiative pathways in their new materials.
This led to a 30% reduction in R&D time for new phosphor formulations and a 15% increase in quantum efficiency for their next-generation displays, translating to millions in cost savings and significant market advantage. The ability to extract physically meaningful rate constants allowed for predictive modeling, minimizing the need for extensive experimental testing.
