✦ Synopsis

Optical Characterization: Fluorescence spectra were measured using a fiber-coupled grating spectrometer (Jobin Yvon Triax 190) equipped with a charge-coupled device (CCD) detector. The dye was excited by a 488 nm continuous wave Ar-ion laser (Spectra-Physics Stabilite 2017). The excitation intensity was kept low to avoid degradation of the dye.

The reflectance spectra of the films were collected on a fibercoupled grating spectrometer (Jobin Yvon Triax 190) spectrometer with incident light normal to the film surface. A bifurcated optical fiber was used, with the output arm attached to the spectrometer and the input arm attached to a Ocean Optics LS-1 Tungsten Halogen light source.
