Abstract Fe 3+ is a promising dopant for designing near‐infrared (NIR) phosphors due to its broadband emitting, non‐toxic, and inexpensive properties. However, the 4 E ( D) + A 1 G) levels of ions are independent crystal‐field parameter, spectral regulation has become huge challenge. Herein, NIR‐emitting phosphor Ca 2.5 Hf (Ga, Al) 3 O 12 : successfully developed toward long‐wave ultraviolet (LWUV) light‐pumped NIR phosphor‐converted LED (pc‐LED). Significantly, excited transition reverse Ga can be realized by simply adjusting concentration, which results in largely enhanced excitation around 410 nm matches well with commercial LWUV LED. Moreover, exhibit emission centered at 770 optimized doping content 0.01 mol%, demonstrated ascribe occupying both octahedral 4+ tetrahedral sites. Further, simple cation modulation strategy proposed break lattice symmetry enhance NIR‐emission intensity 200% as much before. Finally, pc‐LED fabricated employing , Al coating on chip, shows great potential non‐destructive inspection applications.
