"light hits thin silver film, interacts with free electrons on surface creating oscillations (plasmons) concentrating light/ enhancing electromagnetic field, increasing nearby molecules' light absorption 10X, enabling 19X reduced light intensity to trigger conversion compared to previous non-plasmonic systems... built low-energy powered blue OLED prototype (blue normally requires high energy, often leading to instability), then combined with green/ red light for stable white light"
