摘要：

Novel optical sensing films for oxygen based on highly luminescent iridium (111) and ruthenium (11) complexes have been developed. These demonstrate excellent long-term photostability (several months) when incorporated into polystyrene membranes. The influence of different plasticizers on the specific luminescence quantum yield, the Stern-Volmer constant, the reversibility and the response time were evaluated. Additionally the sensing films can be sterilized by chemical cleaning and gamma-ray irradiation. (c) 2006 Elsevier B.V. All rights reserved.
