Optical luminescent spectroscopy, laser confocal microscopy and STM were used to study the structure, luminescent and electrical properties of new metal-organic coordination compounds based on different cellulose derivatives, gold nanoparticles and Tb3+ ions. The layers of cellulose derivatives form compact globular structures on solid surfaces. Their size and shape depend on the nature of substrate and cellulose derivatives. The formation of Tb-cellulose coordination compounds leads to a significant reduction in the globules sizes and some changing of their shape. Local tunneling current-voltage characteristics of the cellulose derivatives and organometallic complexes have essentially non-linear form. In the organometallic complexes the bandgap and the mechanism of tunneling conductance are not changed. But the nature of the substrate has a much stronger influence. On a silver substrate the size of the globules and the band gap increase. Also the mechanism of tunneling conductivity change. Only lines of terbium are observed in the luminescence spectra of Tb-cellulose solutions. However, in the spectra of Tb-cellulose solid layers new intense lines appear at 670-700 nm and 824 nm. Their spectral width depends on the nature of the cellulose derivatives. The presence of gold nanoparticles has no appreciable effect on the position and intensity of the spectral lines. The assignment of the 670-700 nm and 824 nm bands causes difficulty because they do not belong to the terbium lines or cellulose and we could not find any information about the results of similar studies.
