Abstract:Rational design of bright near and shortwave infrared
(NIR: 700–1000 SWIR: 1000–2000 nm) molecular and nanoscale emitters is a
fundamental scientific question with applications ranging from deep tissue
imaging to new photonic materials. However, all reported organic chromophores
with energy gaps in the SWIR have very low quantum yields. Is this the result
of a fundamental limit for the quantum yield of organic chromophores in the
SWIR? Here we combine experiment and theory to derive an energy gap quantum
yield… Show more
