Abstract
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 ( 4 D) and 4 E + 4 A 1 ( 4 G) levels of Fe 3+ ions are independent of the crystal‐field parameter, and the spectral regulation has become a huge challenge. Herein, a broadband NIR‐emitting phosphor Ca 2.5 Hf 2.5 (Ga, Al) 3 O 12 : Fe 3+ is successfully developed toward long‐wave ultraviolet (LWUV) light‐pumped NIR phosphor‐converted LED (pc‐LED). Significantly, the excited transition reverse of Ca 2.5 Hf 2.5 Ga 3 O 12 : Fe 3+ can be realized by simply adjusting Fe 3+ concentration, which results in the largely enhanced excitation around 410 nm…
