At its heart is the nanoparticle on photonic crystal (NPoPC) construct, where metal NPs are placed on the surface of a resonant frequency matched dielectric photonic crystal slab. The delocalized photonic crystal guided resonance (PCGR) traps light for an extended lifetime, and the elevated optical field is further confined into nanoscale volumes via surface plasmon polaritons (SPPs) in metal NPs. The antenna--cavity coupling produces a large field enhancement reaching 100,000 localized at the NPs, which has a narrow resonance linewidth (Q-factor~ 300) and a wide spectral tuning range (visible to near infrared). Mode hybridization leads to dramatic enhancements of photophysics and photochemical process of a nearby molecule, which is demonstrated in two examples. First, compared to a solitary NP, the PCGR-coupled NP can further amplify the surface-enhanced Raman scattering (SERS) of molecules by two orders of magnitude. Second, through an enhanced excitation of energetic charge carriers, the PCGR-coupled NPs can efficiently transfer energy into nearby molecules and catalyze their chemical reactions at a higher rate. The synergy between two polar opposite types of nanophotonic resonant elements achieved in the NPoPC is unique. This work offers important physical insights on bridging the plasmonics and photonics realms, and opens up new opportunities in the exploration of novel phenomena such as sensing, nanochemistry, and quantum optics.","Submission published under a 24 month embargo labeled 'U of I Access', the embargo will last until 2022-05-01","The student, Qinglan Huang, accepted the attached license on 2020-03-25 at 10:57.","The student, Qinglan Huang, submitted this Dissertation for approval on 2020-03-25 at 11:47.","This Dissertation was approved for publication on 2020-03-26 at 14:51.","DSpace SAF Submission Ingestion Package generated from Vireo submission #14913 on 2020-08-25 at 17:27:02","Made available in DSpace on 2020-08-26T23:51:26Z (GMT).
