By employing chemical bath deposition, polycrystalline thin films of CdS were grown on glass substrates. During the process of growth relative volumes of nitrate of erbium penta- hydrate (Er(NO3)35H2O) were added in aqueous solution of CdS in order to obtain different levels of doping, the samples obtained by this method were electrically and optically characterized determining the dark conductivity,...
We demonstrate and present a novel semidrop optical fiber refractometric microsensor, which by contact is capable to distinguishing immiscible liquid interfaces. Microsensor consists of a couple of 8.3/125 monomodal fibers, parallel placed, and with one pair of their ends are joined by electrical arch fusion. In this junction we shaped a glass semidrop, as a half ldquodonutrdquo. 1.55 mum laser beam...
CdS thin films grown on ITO/glass substrates by using chemical bath (CB) were boron-implanted employing 100keV beam of boron ions (B + ) with fluences in the range 1.0×10 15 –1.0×10 16 ions/cm 2 . The B doping was successfully carried out, as was proved by the major carrier density introduced in the range 0.8×10 18 –5.4×10 18 cm −3 , which was...
