N2 - Polyoxometalates (POMs) are an emerging class of materials which can be considered as inorganic complexes with distinct structural and optical characteristics. To be suitable in biomedical applications such as imaging, the materials may need to be embedded in a suitable host material, which may affect the optical properties of the emitting polyoxometalate. Here, we demonstrate that POMs can successfully be included into a sol-gel derived silica matrix. We report on the effects of one such potential host on the luminescence excitation and emission spectra, as well as the POM luminescence decay times. It appears that the POMs do not interact with the bulk oxide of the matrix, but are retained within the hosts' internal pore structure
