Rare Metals, Volume 45, Issue 2, February 2026.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.

Highly Stable CsPbBr3@Cs4PbBr6 Perovskite Fluorescent Nanomaterials for White Light‐Emitting Diodes
Rare Metals, Volume 45, Issue 1, January 2026.ABSTRACT Although halide perovskite nanocrystals exhibit excellent photoelectric properties, their inherent instability greatly limits their practical applications. Here, we report a novel self‐assembly strategy to synthesize highly stable CsPbBr3@Cs4PbBr6 perovskite fluorescent nanomaterials in a single step by using 4,4′‐azo (4‐cyanoglutaric acid, CA)

Gongye shui chuli, 2006 对用4-甲氧基-N-(3-二甲氨基丙基)萘酰亚胺烯丙基氯的季铵盐(4-MNDMAPN-AQ)做荧光标记的丙烯酸/丙烯酰胺(AA/AM)共聚物进行性能评价，研究了pH、氧化剂、常规阻垢剂对荧光强度的影响。实验结果表明:在pH=7-10，常规阻垢剂存在的情况下共聚物的荧光强度稳定，氧化剂作用使其荧光强度减弱，荧光强度与其质量浓度(1-10 mg/L)呈良好的线性关系。共聚物具有良好的阻垢性能。
