Optically transparent electrode optical image

Spectroelectrochemistry [99] Is a hybrid technique resulting from the association of electrochemistry with spectroscopy via the use of cells with optically transparent electrodes [100-103]. The potential of this technique lies in the possibility of Identifying both the type and the amount of the species generated In an electrochemical step. The Intrinsic characteristics of spectroelectrochemistry require the use of fast measuring systems —spectroscopic image detectors in most cases [104-107]— and the consequent acquisition of the large number of data provided by the detection system In a short time by means of an oscilloscope or, even better, of a computer also allowing the subsequent exhaustive treatment of the raw data. 

Another electrode form is a thin film deposited on an optically transparent nondiamond substrate, such as undoped Si for IR or quartz for UV/Vis spectroelectrochemical measurements. Diamond deposition on Si for IR OTEs is rather straightforward and involves growth conditions similar to those described above. The resulting films are 2-4 gm thick with micrometer-sized grains of diamond randomly oriented over the surface. Deposition of thin films of diamond on quartz is a little more involved [118]. Figure 22 shows an optical image of a diamond/quartz OTE. The film has a blue hue to it due to the boron doping level. It is... 

The in situ imaging of biofllms using fluorescent microscopes is a standard technique in biofilm research [143]. The commercial availability of optically transparent electrodes has allowed the use of in situ confocal laser scanning microscopy (CLSM)...
