Amplification of Fluorescent Contrast by Photonic Crystals in Optical Storage

320-fold luminescence enhancement of [Ru(dpp)3]Cl2 dispersed on PMMA opal photonic crystals and highly improved oxygen sensing performance

“…14,15 In particular, not only can three-dimensional (3D) opal or inverse opal PhCs largely enhance the luminescence of dyes but they also have the advantage of easier preparation. As reported by Song's group, 16,17 a 40-fold enhancement in luminescence was observed using 3D PhCs for optical storage, and a 162-fold enhancement was obtained by modulating dual stopband PhCs. As reported by Li's group, 18 a 71-fold enhancement was also observed using 3D PhCs.…”

Organic optical/electrical functional thin films

“…Furthermore, by using the PCs' superior properties in localizing the emission, the sensitivity of DNA detection system based on fluorescence resonance energy transfer were greatly improved, and an ultrasensitivity detection down to 13.5 femtomolar was achieved [14]. More recently, by introducing PCs into optical memory system based on optical gain effect of PCs, a 40-fold enhancement of fluorescence signal and 7-fold on/off ratio amplification were obtained [15] ( Figure 2). …”

Rapid Nanoimprinting of Doped Silk Films for Enhanced Fluorescent Emission

“…[ 8 ] By measuring the scattered light from the nanopatterned surface, a colorimetric sensor responsive to changes of the refractive index between the air and silk patterned interface was demonstrated. [ 9 ] Periodic surface patterning has also gained interest as a strategy to enhance both the excitation and extraction of light for a variety of optical applications such as light emitting diodes, [10][11][12][13] guided mode lasers, [ 14 ] biosensors, [ 15 ] quantum dots, [ 16 ] plasmonics, [ 17 ] optical storage devices, [ 18 ] and nonlinear optics. [ 19 ] However, the use of this approach to enhance the emission of protein-based biopolymers has not been reported to date.…”
