In particular\, s urface plasmons—collective oscillations of electrons at metal surfaces —provide a powerful mechanism for concentrating light into extremely sma ll regions and producing strong local electromagnetic-field enhancement. T hese properties are creating new opportunities for sensing\, imaging\, ene rgy conversion\, and biomedical technologies.\n\nOne emerging frontier in plasmonics is the enhancement of nonlinear optical processes\, including l uminescence upconversion. In upconversion\, lower-energy photons are absor bed and converted into higher-energy emitted light. Unlike conventional no nlinear frequency-conversion processes\, luminescence upconversion can ope rate efficiently under low-intensity\, incoherent illumination. This chara cteristic makes it especially attractive for applications such as bioimagi ng\, biosensing\, and solar-energy conversion\, where traditional nonlinea r optical techniques may be difficult to employ.\n\nThis talk will begin w ith an introduction to surface plasmons\, nanophotonics\, and frequency-up conversion processes. Dr. Park will then describe the electrodynamic princ iples governing luminescence upconversion in nanophotonic environments and present spectroscopic studies of photonically enhanced upconversion. Thes e studies help identify the mechanisms and factors responsible for enhance ment throughout the various stages of the upconversion process.\n\nCo-spon sored by: CH04099 - Southeastern Michigan Chapter\, EMB\n\nSpeaker(s): Won Park\, \n\nAgenda: \n1) 5:00-5:30pm – Come to view the beautiful Ritchi e Engineering Center at DU and enjoy meeting other engineers\, faculty and guests.
