“…The color of light detected by the device can be chosen by selecting a J-aggregate with a corresponding peak absorption wavelength. The layer of carbon nanotubes can also be used to provide photoinduced conductance [222]. Wavelength conversion from visible absorption of J-aggregates to near-IR luminescence (1000-1300 nm) of colloidal Ag 2 S QDs was demonstrated [223].…”

J-aggregates are fascinating fluorescent nanomaterials formed by highly ordered assembly of organic dyes with the spectroscopic properties dramatically different from that of single or disorderly assembled dye molecules. They demonstrate very narrow red-shifted absorption and emission bands, strongly increased absorbance together with the decrease of radiative lifetime, highly polarized emission and other valuable features. The mechanisms of their electronic transitions are understood by formation of delocalized excitons already on the level of several coupled monomers. Cyanine dyes are unique in forming J-aggregates over the broad spectral range, from blue to near-IR. With the aim to inspire further developments, this review is focused on the optical characteristics of J-aggregates in connection with the dye structures and on their diverse already realized and emerging applications.

“…A significant number of them are drawn or derived from compounds originally developed as industrial colourants, laser dyes, or fluorescent probese.g., blue-absorbing coumarins [22,[44][45][46][47], green-absorbing rhodamines [44,45,[48][49][50][51] and quinacridones [11,47,[52][53][54][55][56][57][58][59][60][61][62][63], green-and red-absorbing phthalocyanine metal/metalloid complexes and derivatives [11, 44, 45, 47, 49, 54-56, 58, 61, 64-70], and green-, red-, and NIR-absorbing squaraines [23,[71][72][73] ( figure 4(b)). It is noteworthy that some narrowband-absorbing small molecules are able to form aggregates (Jand H-aggregates) featuring particularly narrow and intense absorption bands (FWHM α <20 nm, α up to 10 6 cm −1 ), a property that is very attractive for narrowband photodetection [24,[74][75][76][77][78][79].…”

The capability of detecting visible and near infrared light within a narrow wavelength range is in high demand for numerous emerging application areas, including wearable electronics, the Internet of Things, computer vision, artificial vision and biosensing. Organic and perovskite semiconductors possess a set of properties that make them particularly suitable for narrowband photodetection. This has led to rising interest in their use towards such functionality, and has driven remarkable progress in recent years. Through a comparative analysis across an extensive body of literature, this review provides an up-to-date assessment of this rapidly growing research area. The transversal approach adopted here focuses on the identification of: (a) the unifying aspects underlying organic and perovskite narrowband photodetection in the visible and in the near infrared range; and (b) the trends relevant to photoconversion efficiency and spectral width in relation to material, device and processing strategies. A cross-sectional view of organic and perovskite narrowband photodetection is thus delineated, giving fresh insight into the status and prospects of this research area.
