The energetic and physical concept of gold nanorod-dependent fluorescence in cancer treatment and development of new photonic compounds|review

“…83,[90][91][92] Even a small change in aspect ratio results in a noticeable shi in the NIR absorption wavelength. [93][94][95][96][97] (SPR) bands are two absorption bands that (GNR) exhibits, one of which is TSPR (transverse) in the visible spectrum, and the other is LSPR (longitudinal) in the near-infrared spectrum (NIR).

Broadband Tunable Mid-Infrared Absorber Based on Conductive Strip-Like Meta-Atom Elements

“…Interaction of electromagnetic radiation with subwavelength metal particles and controlling for optical processes such as absorption and scattering is of great interest for both fundamental science and practical applications [1][2][3]. Particularly, the realization of the high absorption with a simultaneously low scattering in systems consisting of metal particles is important for energy harvesting and conversion [4,5], optoelectronics [6], sensing [7] and investigations of light-matter interactions [8].…”

“…However, the absorption spectrum due to LSPR is usually narrowband. Another approach to shifting the absorption resonance towards longer infrared wavelengths with simultaneously negligible scattering is using core-shell configurations [2,14,18]. The absorption then can be controlled by choosing core and shell materials, as well as by varying geometrical parameters such as core radius or shell thickness.…”
