It is important to keep the spectral properties of lanthanide complex in a thin layer. Because, specific interaction bis phthalocyanine with albumin plays an important role in the evaluation of protein. Band in the absorption spectram (Fig. 9.9) phthalocyanine ytterbium in formed a thin layer is characterized by 664 mu. Spectral shape and position of the absorption band corresponds to the neutral form [16].
