Light-induced absorption changes by excitation of metastable states inNa2[Fe(CN)5

Abstract: The ground state and the light-induced metastable states of Na 2 ͓Fe(CN) 5 NO͔•2H 2 O were investigated by polarized optical absorption spectroscopy on single crystals. An orbital level scheme is proposed for the ground state and the two metastable states SI and SII. Based on polarization analysis of the electronic transitions and density of states calculations using density functional theory ͑DFT͒, three electronic transitions were tentatively assigned to the calculated transitions of the orbital level scheme… Show more

“…The sensitive spectral range reaches from the near ultraviolet to the near infrared and can equally be selected by choosing appropriate compounds. [12,[20][21][22] Note that the photorefractive response is large, for example, up to Dn ≈ 10 -2 in SNP. [18] [14] we can estimate the refractive index change of the former ones to Dn ≈ 10 -3 -10 -4…”

“…In SNP, the generation of the metastable linkage isomers is connected with optical absorption changes, which are known from low-temperature absorption spectroscopy [25]. Therefore the change of the transmitted light intensity during illumination can be used to determine the population numbers of the metastable states, SI and SII.…”

“…Then SI is transferred to SII using infrared light [22]. Using the wavelength 1064 nm, about 60% of the SI population is transferred to SII, while the remaining decay back into the ground state, such that SII populations above 20% can be reached by this procedure [25]. The transfer can be monitored by recording the transmitted light intensity of the infrared light.…”
