Broadband Shortwave Infrared-Emitting Cr3+- and Ni2+-Codoped Y3Al2Ga3O12 Phosphor with Excellent Thermal Stability for Multifunctional Applications

Shortwave infrared (SWIR)-emitting materials have emerged as superior light sources with increasing demand for potential applications in noninvasive analysis, night vision illumination, and medical diagnosis. For developing next-generation SWIR phosphor-converted light-emitting diodes (pc-LEDs), the scarcity of intense blue-light-pumped broadband SWIR luminescent materials and poor thermal stability of current Ni
