Influence of Outcoupling Layers on Top‐Emitting Perovskite Light‐Emitting Diodes
Advanced Optical Materials, Volume 13, Issue 8, March 13, 2025.Top‐emitting perovskite LEDs offer benefits over typical bottom‐emitting architectures, toward lasing, improved thermal management, and on‐chip fabrication compatibility. Outcoupling layers offer a strategy uniquely applicable to top‐emitting LEDs to optimize EQE by improving optical outcoupling.

Locking in Color: Stable RGB Perovskite Nanocrystal Films via UV Cross‐Linking
Advanced Optical Materials, EarlyView.Combining block copolymer stabilized lead halide nanocrystals with a UV light‐based cross‐linking procedure yields ultra‐stable nanocrystal thin films, which are resistant to dissolution by organic solvents and impervious to interlayer ion exchange. This allows for the fabrication of stacked layer RGB all‐perovskite white light‐emitting phosphors with ...

Experimental Biology and Medicine, 1968 SummaryOsteocyte lacunae were measured in normal rats and in rats in which periosteal hypertrophy had been induced at the adductor longus-pectineus insertion. Lacunae in the cortex beneath the periosteal hypertrophy were significantly larger than lacunae in the cortex of the opposite side of the femur from the hypertrophy.

Suppressed Stokes Shifts and Hot Luminescence from Quantum Dots within Plasmonic Nanocavities
Advanced Optical Materials, EarlyView.This study demonstrates the suppression of the Stokes shift in lead sulfide quantum dots through integration with plasmonic nanocavities. By enhancing spontaneous emission and altering exciton relaxation pathways, this approach enables direct band‐edge emission with improved radiative efficiency, highlighting the powerful role of nanophotonic ...

Degeneration of postovulatory follicles in the Iberian sardine Sardina pilchardus: structural changes and factors affecting resorption [PDF]
, 2007 Inaccuracy in the aging of postovulatory follicles (POFs) and in estimating the effect of temperature on the resorption rate of POFs may introduce bias in the determination of the daily spawning age classes with the daily egg production method (DEPM). To

Advanced Optical Materials, EarlyView.This study reveals the critical influence of film thickness and excitation wavelength on the ASE threshold in metal halide perovskites. By optimizing these factors, the ASE threshold is significantly reduced, providing key insights into optical confinement and carrier distribution for advancing electrically pumped perovskite lasers.

Advanced Optical Materials, EarlyView.P‐ or pyrene‐type delayed fluorescence is the original name of triplet‐triplet annihilation. However, pyrene is a poor annihilator. Silylethynyl substitution improves the energetics of pyrene and prevents excimer formation, enabling red‐to‐blue photon upconversion with 29% efficiency. We find tuning substituent steric bulk is key to achieving this high

Excitation‐Wavelength‐Tunable Lasing in Individual Quantum Dot Superparticles
Advanced Optical Materials, EarlyView.Mesoscale superparticles assembled from CdSe quantum dots are shown to behave as microlasers with emission properties that can be tuned by changing the excitation wavelength. Abstract Microcavities enable precise control over light‐matter interactions, supporting a wide range of applications in photonics and optoelectronics.
