In this study, Eu2+/Nd3+ codoped CaSi2O5 phosphors were synthesized via a conventional solid-state reaction route under a reducing environment to explore their potential for bioimaging applications. 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 WilliamsonHall 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 CaO, SiOSi, EuO and NdO bonds. Photoluminescence studies showed an excitation spectrum with distinct and intense absorption bands within the range of 7001000 nm, attributed to the 4f4f 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 (x = 0.155, y = 0.059), indicating high potential for background-free bioimaging with high chromatic accuracy. These findings suggest that Eu2+/Nd3+ doped CaSi2O5 can be a promising luminescent material for advanced biomedical imaging applications. 2025 John Wiley &amp; Sons Ltd.
