The optical properties of two-component films composed of mesotetraphenylporphyrin (TPP) and erbium-doped yttrium vanadate Yt0.95Er0.05VO4 prepared by spincoating have been studied for the first time. A decrease in the TPP content in the films leads to a hypsochromic shift of the Soret band peak by 1–9 nm; this finding suggests that the degree of aggregation of TPP decreases with decreasing TPP content...
Using absorption and fluorescence spectroscopy methods we obtained the results demonstrating alterations in spectral characteristics in supramolecular system composed of gold nanorods (AuNR) (10 × 38 nm) and complexes of human serum albumin (HSA) and 5,10,15,20-tetraphenylporphyrin (TPP). TPP fluorescence (λmax = 636 and 658 nm) was found to enhance. The dependence of fluorescence enhancing in time...
