Over the past decade, perovskite technology has been increasingly applied in solar cells, nanocrystals, and light-emitting diodes (LEDs). Perovskite nanocrystals (PNCs) have attracted significant interest field of optoelectronics owing to their exceptional optoelectronic properties. Compared with other common nanocrystal materials, nanomaterials many advantages, such as high absorption coefficients tunable bandgaps. Owing rapid development efficiency huge potential, materials are considered future photovoltaics. Among different types PNCs, CsPbBr3 perovskites exhibit several advantages. offer a combination enhanced stability, photoluminescence quantum yield, narrow emission bandwidth, bandgap, ease synthesis, which distinguish them from make suitable for various applications photonics. However, PNCs also some shortcomings: they highly susceptible degradation caused by environmental factors, moisture, oxygen, light, limits long-term performance hinders practical applications. Recently, researchers focused on improving stability starting synthesis optimizing (i) external encapsulation crystals, (ii) ligands used separation purification (iii) initial methods or material doping. In this review, we discuss detail factors leading instability introduce enhancement mainly inorganic mentioned above, provide summary these approaches.

Efficient Color Conversion in Metal–Organic Frameworks Boosts Optical Wireless Communications beyond 1 GB/s Data Rate

Journal of the American Chemical Society, Journal Year: 2025, Volume and Issue: unknown

Published: Feb. 11, 2025

Efficient color converters are essential for achieving high −3-dB bandwidths and net data rates in optical wireless communications (OWCs). Here, we emphasize the significance of lanthanide-based metal–organic frameworks (MOFs) combined with an effective energy transfer strategy developing high-performance OWC systems. In this approach, successfully reduced photoluminescence (PL) lifetime from 1.3 ms MOF to 4.6 ns MOF–chromophore composite, achieved through efficient process cavity surface MOFs. This significant reduction PL led a dramatic increase bandwidth, rising less than 0.1 65.7 MHz. Most importantly, rate 1.076 GB/s was achieved, marking first successful demonstration MOFs as that facilitate transmission exceeding 1 GB/s. Notably, both bandwidth surpass those most reported organic inorganic materials, underscoring exceptional potential when strategy. We believe combination paves way further innovations high-speed technologies.
