A Variable Optical Attenuator Operating in the Near-Infrared Region Based on an Electrochromic Molybdenum Complex
Source abstract
Abstract
A dinuclear oxo-Mo(V) complex 1 has been prepared which develops an intense absorption in the near-IR region (λ = 1340 nm; ε = 23 000 M-1 cm-1) on reversible one-electron oxidation to [1]+. This has formed the basis of a variable optical attenuator, whereby the intensity of near-IR laser light may be modulated over a range of 50 dB according to the electrical potential applied to the cell.

18. The OTTLE cell consisted of two indium-doped tin oxide-coated glass slides separated by 0.2 mm thick glass spacers and fixed together with a wax sealant. The cell was filled with a 0.9 × 10-3M solution of1in acetonitrile with 0.1 M [n-Bu4N]PF6as electrolyte. No attempt was made to exclude air.
19. The cell used for VOA measurements consisted of two indium-doped tin oxide-coated glass slides separated by a 6 mm thick Teflon spacer. The cell was filled with a 3 × 10-4M solution of1in acetonitrile with 0.1 M [n-Bu4N]PF6as electrolyte. No attempt was made to exclude air.
