Abstract:
Photoluminescence spectra of organic semiconductors based on mono-, bis-, and triphthalocyanine containing erbium as a complexing agent have been obtained in the range of 1–1.8 μm. Comparison of the spectral characteristics has shown that erbium triphthalocyanine has the highest photoluminescence quantum yield at a wavelength of 1.5 μm. To enhance this effect, composite materials based on erbium triphthalocyanine and a silicon slot structure have been synthesized, in which an additional increase in the photoluminescence signal near 1.14 μm has been observed. At the same time, no photoluminescence signal has been observed near the wavelength of 1.5 μm. This can be explained by taking into account the interaction of the erbium triphthalocyanine molecules with the adsorption centers of the silicon matrix.
