Electrochromic Properties of Sol-gel Coating of Nb2O5 and Nb2O5:Li+ [PDF]

Materials Research, 2002
Thin solid films of Nb2O5 and Nb2O5:Li+ were prepared by the sol-gel process using the sonocatalytic method. The films reported here were prepared from a NbCl5 as precursor and butanol as solvent. Through the addition of lithium salt LiCF3SO3 to the precursor solution, films with different electrochemical performance were obtained.
