Due to their chemical stability, finely tunable plasmon resonances, and large light absorption cross sections, Au nanocages are ideal NIR-MEF agents.
Due to their chemical stability, finely tunable LSPR in the NIR, and large light absorption cross sections (much higher than typical organic dyes), Au nanocages are ideal MEF agents.
For spheres smaller than the wavelength of the incident light, the absorption cross section may be estimated by calculating the dipole contribution to the absorption spectra as: γ = 9 ε α 3 ∕ 2 V ( ω ∕ c ) ε 2 ∕ { [ ε 1 + 2 ε 2 ] 2 + ε 2 2 } (2).
It is determined by the product of light intensity and absorption cross section which are therefore probed simultaneously.
This intensity is higher than the reported value of 50 W/m2 in the experiment to ensure that the light is still saturating when the absorption cross section of the LHCs is reduced during the optimization.
They are efficient in photon-to-thermal conversion due to the surface plasmon resonance (SPR) oscillation and high absorption cross section of NIR light.
The total number of electrons in the excited states per time interval d t, d nexcited, is provided by photon absorption, and is thus described by the absorption cross section, σ by the light intensity, I t), and the number of electrons in the ground state, nground.
Such domestication strategies include decreasing the absorption cross section in order to enhance light penetration, increasing the size of metabolic sinks per chlorophyll and minimizing feedback energy dissipation.
Among these, chalcogenide semiconductor quantum dots have some unique properties, such as quantum size effect, high fluorescence efficiency, large absorption cross section (1.1 × 10− 18 cm− 2), light stability, rendering them as excellent candidate materials [15 18].
where n represents the number of absorbers, γ is the absorption cross section, and I o is the incident light intensity.
