Optical properties of Er3+ doped alkali-chloro phosphate glasses for optical amplifiers
K. Pradeesh, C. J. Oton, V. K. Agotiya +2
A new class of Erbium doped glasses with compositions xNa2O - (60-x)PbCl2 - 40P2O5 (x=0, 10, 20 and 30) were fabricated and characterized for optical properties. Absorption spectra…
Role of microstructure in porous silicon gas sensors for NO
Zeno Gaburro, Paolo Bettotti, Massimo Saiani +4
Electrical conductivity of porous silicon fabricated form heavily doped p-type silicon is very sensitive to NO, even at concentrations below 100 ppb. However, sensitivity stron…
Opposite effects of NO on electrical injection in porous silicon gas sensors
Zeno Gaburro, Claudio J. Oton, Lorenzo Pavesi +1
The electrical conductance of porous silicon fabricated with heavily doped p-type silicon is very sensitive to NO. A concentration of 10 ppb can be detected by monitoring the c…
