The results of a study of the use of non-destructive contact-free optical spectroscopy — registration of UV-VIS-NIR-range diffuse reflection spectra and photoluminescence spectra — for the identification of porcelain products are reported. Based on the color characteristics and a list of optically active centers of luminescence (OALC) porcelain products were graded according to the composition and state of the redox medium during firing. It is shown that the chromaticity of porcelain can be controlled by means of a combination of color and luminescence centers and their intensity ratio. A decrease in the intensity of the OALC Fe³⁺ band is mainly related to a change in the coordination of iron Fe³⁺O₄ → Fe₃₊O₆ in bone china.

报告了使用非破坏性无接触光谱技术进行研究的结果（UV-VIS-NIR范围的漫反射光谱和光致发光光谱的配准），用于鉴定瓷器产品。根据颜色特征和光学活性发光中心（OALC）列表，根据烧制过程中氧化还原介质的组成和状态对瓷产品进行分级。结果表明，可以通过颜色和发光中心及其强度比的组合来控制瓷器的色度。OALC Fe ^3+能带强度的降低主要与铁Fe ³⁺ O ₄ →Fe ₃₊ O ₆的配位变化有关。 在骨瓷中。
