Conventional Cr

-doped near-infrared (NIR) phosphors suffer from severe thermal quenching, which restricts their practical deployment in high-power NIR phosphor-converted light-emitting diodes (NIR pc-LEDs). Most existing research merely focuses on optimizing spectral profiles and quantum efficiency, while systematic investigations on improving high-temperature anti-quenching performance remain scarce. In this work, we synthesized trigonal BaCa

(BCMS) silicate phosphors featuring a highly rigid lattice framework. Multiple characterization techniques were adopted to comprehensively analyze the crystal structure, luminescence performance, thermal stability and device practicability of the as-prepared materials. Characterization results reveal that Cr
3+
ions preferentially occupy the six-coordinated Mg
2+
octahedral sites in the lattice, forming a single luminescent center. The phosphor exhibits broadband NIR emission covering 650-1 000 nm with an emission peak at 803 nm under blue light excitation. Benefiting from the rigid structural network constructed by compact [MgO
6
] octahedra constrained by surrounding [SiO
4
] tetrahedra in the host matrix, high-temperature nonradiative transitions are drastically suppressed. At 423 K, the luminescence intensity retains 90.84% of its room-temperature value, and no obvious luminous degradation is observed during prolonged high-temperature operation. The packaged NIR pc-LED device exhibits an approximately linear increase in output optical power with rising driving current, manifesting favorable overall operating performance. In summary, the highly rigid BCMS-based phosphor effectively alleviates the intrinsic thermal quenching drawback of traditional Cr³⁺-activated NIR materials, rendering it promising for extensive applications in high-power NIR solid-state light sources, biolog
ical imaging, nondestructive testing and other related fields.
