A Comprehensive Review of Adsorbents for Rare Earth Separation: Design, Synthesis, Adsorption Performance, and Mechanisms

Rare Metals, EarlyView.
ABSTRACT Rare earth elements (REEs) play an irreplaceable role in modern technology and industry. However, due to the highly similar physicochemical properties among REEs, their separation remains a significant challenge. Additionally, REEs often exist in low‐concentration solutions, making efficient REE recovery an urgent task.

Breaking Concentration Quenching for Excellent Highly Efficient and Stable Narrowband Luminescence by Structural Ordering and Defect Regulation

Rare Metals, EarlyView.
ABSTRACT Enhancing the performance of phosphor materials for wide‐color‐gamut and high‐brightness phosphor‐converted light‐emitting diodes (pc‐LEDs) represents a critical materials challenge. Improving quantum efficiency (QE) under concentration quenching constraints and maintaining thermal stability remain primary objectives.

High‐Brightness Delayed Imaging Realized by Embedding Zinc Gallate Nanocrystals Into Glass

Rare Metals, EarlyView.
ABSTRACT X‐ray delayed imaging technology leverages an “irradiation‐storage‐thermally stimulated readout” mode, demonstrating unique advantages in intermittent monitoring scenarios such as high‐temperature/high‐radiation environments. This typically requires materials combining abundant carrier‐trapping energy levels with structural thermostability ...

Broad‐Spectral Response Lead Halide Perovskite Solar Cells Through Integration of Multifunctional Organic Bulk‐Heterojunction and Quantum‐Cutting Downconversion Materials

Rare Metals, EarlyView.
ABSTRACT Expanding near‐infrared (NIR) spectral response and utilizing ultraviolet (UV) photons are effective strategies for enhancing the power conversion efficiency (PCE) of lead halide perovskite solar cells (PSCs). However, the range of NIR spectral response extension and the utilization of UV light for devices are not enough, and the loss of ...
