Abstract

New optical oxygen sensor based on the quenching of triplet-triplet (T-T) absorption of fullerene (C₆₀) molecules by oxygen using laser flash photolysis has been developed. The lifetime of T-T absorption of C₆₀ in polystyrene decreases with an increase of oxygen concentrations. A Stern-Volmer plot of C₆₀ exhibits considerable linearity (r²=0.999) and K₈₈ is estimated to be 0.50 %^-1, indicating that C₆₀ film is high sensitive oxygen sensor.
