Structure of PLC
Reflection spectra of inverse opal film by infiltration (1) and inverse opal film infiltrated with PLC (2). The inserted figure is a SEM image of the inverse opal film without PLC.
Polarized absorption spectra of PLC film before (solid line) and after (broken line) irradiation of LP light of laser. and were measured with polarizer parallel and perpendicular to the polarization of the laser light. The inserted figure shows the change in the transmitted light intensity of the PLC film between crossed polarizers by irradiation of LP and CP lights of laser.
Change in the reflection spectra of the inverse opal film infiltrated with PLC by LP light irradiation (a). Before irradiation (—), after LP light irradiation for (-----), and subsequent irradiation of CP light for (⋯⋯⋯⋯). Reflection spectra after LP light irradiation for (b). Without polarizer (-----), with parallel polarizer (—), and with perpedicular polarizer (⋯⋯⋯) to the polarization direction of LP light.
Changes in wavelength of reflection band of the inverse opal film infiltrated with PLC. Laser powers were (circle) and (square).
