By slow evaporation method, optically transparent crystals of tetramethylammonium manganese chloride were grown on the surface of porous silicon. By means of scanning electron microscopy and FTIR spectroscopy, the formation of the hybrid structure of porous silicon–[N(CH3)4]2MnCl4 has been confirmed and its composition has been investigated. Photoluminescence excitation and emission spectra of the obtained hybrid structures were investigated in 220 – 400 and 400 – 800 nm regions, respectively. It was established that multicolor photoemission is produced by combining the luminescent radiation bands of porous silicon nanostructures and tetramethylammonium manganese chloride. The possibility of photoluminescence spectra modification by changing the excitation energy is demonstrated.
