“…The other disadvantage of semiconductors or MOFs is that only the UV or limited visible light could be absorbed due to their large band gap. To broaden the absorption region, one feasible pathway is to develop a composite photocatalyst by the combination of semiconductors or MOFs with upconversion nanoparticles (UCNPs). , Owing to the anti-Stokes shift behavior, the visible and UV light could be emitted by UCNPs with the excitation of near infrared (NIR) light. Then, the emitted light is absorbed by the MOFs or semiconductors to widen their light harvesting range.…”

Photocatalysis is a promising pathway to degrade pollutants in water. Although numerous photocatalysts have been developed to remove organic dyes in water, the degradation of antibiotics is still a perplexing problem due to their excellent stability. The hybrid photocatalyst upconversion nanoparticle (UCNP)/metal–organic framework (MOF) has been developed with the aim to utilize the full solar light. However, the low upconversion efficiency results in an unsatisfactory photocatalytic activity. A novel core–shell–shell UCNP, NaYF4:Yb/Tm@NaYF4:Yb@NaYF4 (Tm@Yb@Y), is synthesized to increase the upconversion efficiency. Both the active and inert shells are introduced in the UCNPs, which not only are favorable to weaken the surface quenching but also are helpful to prompt the energy transfer back. As a result, the UC emission intensity is greatly improved as compared with Tm or Tm@Yb. Then, Tm@Yb@Y is combined with NH2-MIL101(Fe) (NMF) to fabricate the novel photocatalyst Tm@Yb@Y/NMF. It exhibits an excellent photocatalytic activity to degrade rhodamine B (RhB), levofloxacin (OFL), and tetracycline hydrochloride (TC). The contribution of near infrared (NIR) light and inert shell on the whole photocatalysis is considered. The possible photodegradation mechanism is proposed according to the photoelectrochemical measurements, free radical and hole trapping experiments, and pump power dependence of upconversion emission intensities. The outstanding performance of Tm@Yb@Y/NMF should be attributed to the synergistic effect including the wider light absorption range, increased UC emission intensity, and feasible electron–hole separation.

“…Among them, the lanthanide-doped UCNPs have attracted great interest due to their unique photophysical properties of remarkable chemical stability, resistance to photobleaching, low toxicity, and the ability to convert NIR light into shortwave light in the UV-visible range [42]. UCNPs have been extensively applied in many areas, including photovoltaics [43][44], biosensing and bioimaging [45][46], drug delivery [47], photodynamic therapy [48][49], etc. [50].…”

Near-infrared (NIR) light-driven photoelectrochemical (PEC) sensing is a highly promising analytical technique, especially for in situ bioanalysis, due to the deep penetration capability and minimal invasiveness of NIR light. In this mini review, we provide a brief overview of recently developed NIR PEC sensors, focusing on NIR light-responsive materials and the representative applications of this type of PEC sensor. Future perspectives for NIR PEC sensors are also described.

“…All-inorganic lead halide perovskites, which typically adopt structures of CsPbX 3 (X = Cl − , Br − , I − ), have drawn extensive research interest in optoelectronics devices because of their excellent optoelectronic properties [1][2][3][4], such as wide absorption range [5,6], strong light absorption ability, long-range electron/hole diffusion length [7], and the advantage of low-cost preparation method [8][9][10]. They have been proved to be ideal materials for fabricating photodetectors (PDs) [9,11], solar cells [12], light-emitting diodes (LEDs) [13,14], etc. Perovskite quantum dots (QDs) are an important branch of perovskites and have emerged as a new class of optoelectronic materials owing to their characteristics including high luminescence with narrow emission bandwidths [11,[15][16][17], size-dependent bandgaps [18], excellent absorption properties [4,10,19], and more importantly, relatively high stability [13,20,21].…”

Self-powered photodetectors based on CsPbBr3 quantum dots/organic semiconductors/SnO2 heterojunction for weak light detection

All-inorganic lead halide perovskite quantum dots (QDs) show great potential in the development of photodetectors (PDs) due to their excellent photoelectric properties. However, the photoresponse performance of the pure perovskite QDs-based PDs is usually limited by the poor charge transport efficiency of the perovskite QDs films. Here, high-performance self-powered PDs based on perovskite QDs and organic semiconductor PQT-12 (poly(3,3'''-didodecyl quarterthiophene)) are reported. Even in a self-powered mode, the devices can still show stable photoresponse to light signals and achieve excellent photodetection performance, including a detectivity up to 5.8 × 10 12 Jones, and I light /I dark ratio up to 10 5 . More importantly, the devices exhibit obvious photoresponse to weak light with intensity as low as 3 nW cm −2 . To the best of our knowledge, the weak light detection ability of the device is better than most reported PDs based on perovskite QDs. In addition, the devices can be fabricated into flexible PDs with almost unchanged photocurrent under different bending angles. The overall performances of our devices are excellent among the reported self-powered PDs. This method utilized here provides new guides for developing high-performance self-powered PDs based on perovskite QDs for weak light detection.
