“…Therefore, codoping both Mn 2+ and Yb 3+ ions into perovskite NCs can serve as a unique model system for studies of host-to-dopant and inter-dopant energy transfer mechanisms, as well as associated radiative and nonradiative decay pathways at each step. Most importantly, such codoped NCs with multiple emission channels hold a high potential to be applied in a wide range of applications, [45][46][47][48][49][50][51][52][53][54][55][56][57][58][59][60][61] including multiplexed biological labelling and sensing, [59] multi-channel photodetectors, [60] stimuli-responsive inks for coding, encryption and decryption, [61] and photon management devices. [45][46][47][48][49][50][51][52][53][54][55][56][57][58] Herein, we report a facile synthesis of Mn 2+ /Yb 3+ codoped CsPbCl 3 perovskite NCs (Scheme 1) through a hot-injection method.…”

Doping metal ions into lead halide perovskite nanocrystals (NCs) has attracted great attention over the past few years due to the emergence of novel properties relevant to optoelectronic applications. Here, the synthesis of Mn2+/Yb3+ codoped CsPbCl3 NCs through a hot‐injection technique is reported. The resulting NCs show a unique triple‐wavelength emission covering ultraviolet/blue, visible, and near‐infrared regions. By optimizing the dopant concentrations, the total photoluminescence quantum yield (PL QY) of the codoped NCs can reach ≈125.3% due to quantum cutting effects. Mechanism studies reveal the efficient energy transfer processes from host NCs to Mn2+ and Yb3+ dopant ions, as well as a possible inter‐dopant energy transfer from Mn2+ to Yb3+ ion centers. Owing to the high PL QYs and minimal reabsorption loss, the codoped perovskite NCs are demonstrated to be used as efficient emitters in luminescent solar concentrators, with greatly enhanced external optical efficiency compared to that of using solely Mn2+ doped CsPbCl3 NCs. This study presents a new model system for enriching doping chemistry studies and future applications of perovskite NCs.

“…A viscous suspension of NCs mixed with toluene and polystyrene was deposited on PMMA by doctor blade and the emissive properties of small prototypes were characterized. [182] Nikolaidou et al used (CH 3 NH 3 PbI 3-x Cl x ) as emitter in thin-film devices on 1.5 × 1.5 × 0.1 cm ITO substrates (G = 1.5) and reported a η opt up to 30% (C = 0.45) under solar illumination. [183] More recently, the same group reported a η opt of 34.7% for a perovskite LSC of unspecified dimensions.…”

Luminescent solar concentrators (LSCs) are optical systems that absorb, convert, and concentrate solar light by means of photoluminescence of an emitting material embedded in a transparent waveguide. LSCs combine large possibilities of variation of shape, flexibility, color, and transparency and can operate under direct or diffuse light. LSCs were actively investigated in the period 1975–1985 in view of photovoltaic (PV) conversion. After 20 years of sleep, research on LSCs has reemerged in the first years of the millennium driven by their potential application for PV conversion in built environment. Research on LSCs aims at the development of new active and passive components, namely emitting and light‐guiding materials, and at the reduction of the loss factors associated with the elemental processed involved in the operation in order to improve power conversion efficiency. After a brief historical account, the operating principles, characterization, components, technology, and applications are reviewed. Finally, the performance of LSCs are critically discussed in a global perspective with particular emphasis on the basic contradiction between light concentration and conversion efficiency leading to some suggestions for future development of the topic.

A novel triphenylphosphine (TPP) treatment strategy was developed to prepare the near‐infrared emission CsPbI3 nanocrystal (NC)‐polymer composite thin‐film luminescent solar concentrators (LSCs) featuring high absolute photoluminescence quantum yield (PLQY), low reabsorption, and high stability. The PL emission of the LSCs is centered at about 700 nm with 99.4±0.4 % PLQY and narrow full width at half maximum (FWHM) of 75 meV (30 nm). Compared with LSCs prepared with classic CsPbI3 NCs, the stability of the LSCs after TPP treatments has been greatly improved, even after long‐term (30 days) immersion in water and strong mercury‐lamp irradiation (50 mW cm−2). Owing to the presence of lone‐pair electrons on the phosphorus atom, TPP is also used as a photoinitiator, with higher efficiency than other common photoinitiators. Large‐area (ca. 75 cm2) infrared LSCs were achieved with a high optical conversion efficiency of 3.1 % at a geometric factor of 10.
