Porcelain samples were studied by the method of time-resolved luminescence with excitation by a molecular nitrogen laser. In the photoluminescence spectra of hard, soft and bone china, a combination of bands of optically active centers was revealed: intrinsic O * Si and O * Al and impurity centers Mn 2+, Cr 3+, Fe 3+, Dy 3+, Sm 3+, as well as molecular [UO 2] 2 +. The OAC Fe 3+ band, differing in intensity, was identified in all porcelain samples
