Effects of NiO, SnO and Ni-doped SnO semiconductor metal oxides on the oxygen sensing capacity of HTPP.

Improving the performance of optical oxygen sensors can be accomplished by adding metal oxide semiconductors (MOSs) additives to the composition comprising an oxygen-sensing agent immobilized in a polymeric thin film. For several decades, MOSs have attracted great interest in gas sensors due to their high sensitivity to many target gasses. Herein, meso-tetraphenylporphyrin (HTPP) dye was immobilized into the poly(1-trimethylsilyl-1-propyne) (poly(TMSP)) silicone rubber in the presence of NiO, SnO, Ni:SnO metal oxide particles as additives, and their thin films were prepared to investigate oxygen-sensitive optical chemical sensor properties.
