Room-temperature phosphorescence from mesoporous silica is observed, with the emission persisting for seconds after switching off the excitation.
Such mesoporous silica materials, including both powders and monoliths, with strong phosphorescence could find promising applications as low-density and eco-friendly phosphors and optically detectable drug carriers.
