Scattering and absorption of light by homogeneous BiFeO3 and hybrid BiFeO3/Au core/shell spherical nanoparticles: A computational study

The optical properties of dumbbell-type nanorods for solar photothermal conversion

“…The dimensionless absorption efficiency and scattering efficiency can be used to characterize the optical response of NPs as 44 where σ is the projected area of the NP. It is worth noting that FEM has limitations and the random distribution of nanoparticles in water.…”

Theoretical investigation of optical properties of optimal architectures of magnetoplasmonic nanoparticles in human tissue for potential applications in photothermal therapy

“…The theoretical expressions of the Mie coefficients for a spherical core/ shell nanoparticle embedded in a non-absorbent matrix are developed in our recent work [23]. Using commercial MATLAB software, we have computed numerically the Mie coefficients and hence the scattering and absorption efficiencies.…”

“…Five types of gold nanoparticles were synthesized and entered the preclinical testing phase, namely gold nanorods [11,12], gold nanospheres [13], gold nanoshells [14], gold nanocages [15,16] and gold nanostars [17,18]. These findings have stimulated numerous theoretical studies dedicated to the design of gold-based plasmonic nanoparticles that best meet the optimal requirements of the PTT technique and also at an affordable cost [19][20][21][22][23][24][25][26][27]. The dominant idea in these works is to design a hybrid nanostructure made up of gold and metallic, dielectric or magnetic material.…”

Optical Properties of Plasma Dimer Nanoparticles for Solar Energy Absorption

“…The optical response of nanoparticles is characterized by the two dimensionless quantities, scattering efficiency Q sca and absorption efficiency Q abs [ 43 ]. Moreover, the scattering and absorption efficiency of the nanoparticle can be given by [ 44 ] where σ sca and σ abs are the absorption and scattering cross-sections, which represent the ratio of total scattering and absorption intensity to incident light intensity, respectively; I 0 is the intensity of the incident light; n is the normal vector; S sca is the scattered intensity vector; Q is the power loss density; S is the surface area of the nanoparticle; V is the volume of the nanoparticle; and σ is the projected area of the nanoparticle.…”
