Green-emitting Mn${}^{2+}$-doped zinc silicate nanophosphor was synthesized by solvothermal method with the assistance of polyvinyl alcohol (PVA). The structure, morphology and optical properties of phosphors were characterized by X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), Scanning electron microscope (SEM), Fourier transform infrared spectrometer (FT-IR) and Photoluminescence Spectroscopy (PL). Also, the application of Mn${}^{2+}$-doped zinc silicate phosphor in electronic devices was studied. Furthermore, Zn₂SiO₄: Mn${}^{2+}$ phosphor was used to be a fluorescent sensor for the first time to detect inorganic ions and small molecules. The results indicated that pure $\alpha$-Zn₂SiO₄ phase nanoparticles with spherical morphology were obtained. The results also showed that the phosphor has excellent selectivity and sensitivity for detecting Cr${}^{3+}$ ions, Cr₂O₇${}^{2-}$ ions and 4-nitrophenol (4-NP) with low detection limits (Cr${}^{3+}$ ions: 1.34 $\mu$M, Cr₂O₇${}^{2-}$ ions: 5.86$\mu$ M, 4-NP: 2.38 $\mu$M). Thus, Mn${}^{2+}$-doped zinc silicate manganese phosphor has potential applications in light-emitting diodes (LEDs) and fluorescent sensors.
