Title: 'High resolution vehicle emissions modelling'
Deadline: 20 July 2018
From: David Hann, Faculty of Engineering, University of Nottingham, 19/6/18
Subject: Help with dyes
'We are looking for some fluorescent dyes that can dissolve in several different types of oils. With all the members here it is possible someone out there has solved this problem already. If you have experience of this and can help please contact me at David.Hann@nottingham.ac.uk
The specifications are as follows.
(1) The fluorescent dye needs to fully dissolve in the working liquids (ideally without the use of solvents). Our working liquids will be AeroShell Turbine Oil 390, Eastman 2197 oil and silicon oil.
(2) The dye’s maximum absorption wavelength should be close to the working wavelength of the lasers that we have available (532nm and 450nm, with preference to the 532nm laser).
(3) The dye should be thermally stable (i.e. its fluorescence should be independent of temperature – worst scenario possible consists on temperatures ranging from 30-130°C ).
(4) The intensity of light recorded upon excitation of the dye needs to be proportional (ideally linearly) to the range of film thicknesses that are to be measured (around 0-4mm).
If point (3) is not fulfilled, there might be a way to compensate for the dependence of fluorescence with temperature.'
