Abstract

En 中文

• XGBoost model links T50 to structural rigidity (ΘD) and bandgap as key factors; • The screened YAl3(BO3)4:Eu3+ achieves 87% PLQY & 93% thermal stability at 450 K with 100% Eu3+ doping. • White pc-LED achieves 38.91 lm/W, among the most efficient near-UV warm white trichromatic systems.
