Morphology of SnO2 thin films obtaibed by the sol-gel technique

Excitation process and photoluminescence properties of Tb3+ and Eu3+ ions in SnO2 and in SnO2: Porous silicon hosts

“…The whole preparation of undoped and antimony (Sb)-doped SnO 2 sol-gel solutions has been presented in previous papers [6][7][8] and kept unchanged for the present work. For undoped SnO 2 , 8.37 g of SnCl 2 :2H 2 O were dissolved in 100 ml of absolute ethanol.…”

Structural, optical and electrical properties of porous silicon impregnated with SnO 2 :Sb

“…The current density and the HF concentration are chosen in order to form PS layers having 70% or 80% porosity with a thickness less than 2 µm. The SnO 2 doped Sb was prepared by the sol-gel technique [8]. The concentration of Sb is estimated to 5% in relation with the Sn content in the sol.…”

Synthesis, characterization and gas sensing performance of SnO2 thin films prepared by spray pyrolysis

“…These include spray pyrolysis (Paraguay et al 1999), ultrasonic spray pyrolysis (Blandenet et al 1981), chemical vapour deposition (Baranauskas et al 2002), activated reactive evaporation (Randhawa et al 1981), ion-beam assisted deposition, sputtering (Vossen and Poliniak 1972), * Author for correspondence (gotanjain@rediffmail.com) and sol-gel (Chatelon et al 1994;Oreal et al 1994) methods. Among these techniques, spray pyrolysis has proved to be simple, reproducible and inexpensive, as well as suitable for large area applications.…”
