We studied 1-dimensional (1-D) photonic crystal (PC) films with three alternating layers to investigate multi-mode photonic band-gaps (PBGs) at red, green, and blue color regions. From simulations, it was shown that PCs with three alternating layered elements of [a/b/c] structure have sharp PBGs at the three color regions with the central wavelengths of 459 nm, 527 nm, and 626 nm, simultaneously. Experimentally, it was proven that red, green, and blue PBGs were generated clearly by the PCs, which were made of multilayers of [SiO2/Ta2O5/TiO2], based on the simulation. It was also shown that the measured wavelengths of the PBGs corresponded exactly to those of the simulated results. Moreover, it was demonstrated that a 1-D PC of [a/b/c] structure can be used for making white organic light emitting devices (OLEDs) with improved color rendering index (CRI) for color display or lighting.
