A series of Cr³⁺-doped ZnWO₄ phosphors exhibiting broadband NIR emission was synthesized via a high-temperature solid-phase method. The photoluminescence (PL) excitation (PLE) spectrum of ZnWO₄: Cr³⁺ exhibits two absorption bands in the 200–400 nm and 400–600 nm ranges, which match well with near-ultraviolet and blue LED chips. Under excitation, the PL spectrum shows a broad NIR emission extending from 700 to 1400 nm, with a full width at half maximum (FWHM) of approximately 210 nm. The internal quantum efficiency (IQE) was measured to be 55.36%. At 373 K, the integrated emission intensity of ZnWO₄: 0.05Cr³⁺ is about 47.5% of that at room temperature (RT). Additionally, a prototype NIR pc-LED device was fabricated by embedding the ZnWO₄: 0.05Cr³⁺ phosphor into a silicone matrix and coupling it with a 450-nm blue LED chip. The device delivered an output power of 17.12 mW at a 140-mA driving current and a photoelectric conversion efficiency of 14.42% at 20 mA.

Calcium silicate, known for its intrinsic biocompatibility, served as the host matrix, whereas Eu²⁺ acted as the primary luminescent centre and Nd³⁺ was used as the near-infrared (NIR) sensitizer to support deep-tissue excitation. Structural analysis via X-ray diffraction (XRD) verified the formation of a triclinic crystal structure and the average crystallite size was validated through both Scherrer equation and Williamson–Hall analyses. Field emission gun scanning electron microscopy (FEG-SEM) images revealed flower-like microstructures with embedded fine white particles. Energy-dispersive X-ray spectroscopy (EDX) detected the existence of expected chemical components of the phosphor, whereas Fourier-transform infrared (FTIR) spectra provided evidence of successful dopant incorporation through characteristic vibrations corresponding to Ca–O, Si–O–Si, Eu–O and Nd–O bonds. Photoluminescence studies showed an excitation spectrum with distinct and intense absorption bands within the range of 700–1000 nm, attributed to the 4f–4f transitions of Nd³⁺ ions, and upon excitation at approximately 800 nm, the phosphor exhibited dual emission bands around 410 and 440 nm with optimal intensity corresponding to the characteristic 4f⁶5d¹ → 4f⁷ transitions of Eu²⁺. The afterglow decay analysis showed persistent luminescence exceeding 15 min, and CIE chromaticity analysis confirmed that the emission lies within the blue spectral range (<i>x</i> = 0.155, <i>y</i> = 0.059), indicating high potential for background-free bioimaging with high chromatic accuracy.

We further evaluated the activation of the NRF2 signaling pathway in human hepatoma HepG2 cells. The pressurized water extract demonstrated typical, dose-dependent NRF2 activation without cytotoxicity.
