The specular transmittance
spectra were recorded from 350 nm to 800 nm using the light from a 300 W xenon arc lamp chopped at 210 Hz, which passes through an Oriel Cornerstone 2601/4 monochromator and illuminates a calibrated photodiode with a transconductance amplifier that is connected to an Oriel Merlin digital lock-in amplifier.
