论文摘要
我们已经在罗伯特·福克（Robert Falk，1907年）的“桦树春天”绘画的油漆层中检测到埃及蓝色颜料。我们还发现这种颜料是在画布背面画的草图的油漆中。这可能是20世纪艺术作品中埃及蓝的第一个发现。 我们已经分析了现代商业埃及蓝色色素（Kremer），并发现它是光致发光光谱分析的标准。 cacusi $ _4 $ o $ _ {10} $的特征光发光带在约910 nm的波长下达到最大值。通过不连贯的绿色或蓝光有效激发发光。 该研究表明，使用不连贯光激发的光致发光光谱微观分析可以有效地用于鉴定艺术品油漆层中的发光色素。
We have detected Egyptian blue pigment in the paint layer of the "Birch. Spring" painting by Robert Falk (1907); we have also found this pigment in the paints of the sketch drawn on the canvas back side. This is probably the first discovery of Egyptian blue in a 20th century work of art. We have analyzed a modern commercial Egyptian blue pigment (Kremer) and found it to be suitable as a standard for photoluminescence spectral analysis. The characteristic photoluminescence band of CaCuSi$_4$O$_{10}$ reaches maximum at the wavelength of about 910 nm. The luminescence is efficiently excited by incoherent green or blue light. The study demonstrates that the photoluminescence spectral micro analysis using excitation by incoherent light can be efficiently used for the identification of luminescent pigments in paint layers of artworks.
