Abstract

We have developed a quantum efficiency measurement system of pressure-sensitive paint (PSP) using an integrating sphere. The quantum efficiency is an index representing the energy efficiency of the luminescence emission. This can be used to measure the luminescent efficiency of PSPs, which have different luminophores, binders, emission and excitation wavelengths. As a user's point of view, the quantum efficiency gives us important information to select a PSP as a component of the PSP measurement system. The quantum efficiency enables us to select a PSP as a component of the PSP measurement system. The quantum efficiency measurement system is described in this paper. The measurement results of the efficiencies of nine PSP sensors, which consist of the binders and luminophores, are also included. The binders are selected from a porous matrix: anodized aluminum, thin-layer chromatography plate, and polymer ceramic. The luminophores are used as a conventional PSP: bathophen ruthenium, pyrene butylic acid, and platinum porphyrin. The quantum efficiency is dependent on the binder and luminophore selected. The highest quantum efficiency is shown by the PSP of bathophen ruthenium on polymer ceramic. It is found that the quantum efficiency is related to the pressure; with increase of the pressure, the efficiency decreased. The trend is the same as the intensity-pressure relationship based on the Stern-Volmer equation.
