Paper Abstract

Multilayer structures of alternating polymers, poly(9-vinylcarbazole) and poly(vinyl alcohol), with reflectance peaks centered in the range 500 - 610 nm, have been deposited on silica glass subtrates by spin-coating. The dependence of their reflectance, transmittance and absorbance on the incident wavelength have been characterized by spectrophotometry. Feedback from a similar characterization on thin single layers (≈ 100 nm), together with the evaluation of thicknesses by a non-contact profilometer, have provided the input parameters to modelize numerically the spectral response of structures with 5 or 10 pairs of layers. Despite the approximations assumed, good agreement among theory and experiment has been achieved, opening the way to perform easy and inexpensive resonant cavities, in which the properties of spontaneous emission might be controlled.
