Abstract

This study investigates the influence of synthesis conditions on structural, morphological and optical properties of chromium-doped hydroxyapatite nanoparticles (Cr-HAp) for UV protection. Using co-precipitation and hydrothermal methods, Cr-HAp nanoparticles with elongated monocrystalline needle-like structures were successfully synthesised. Quantum chemical calculations provided insights into the oriented attachment process and the interaction of ions with the nanoparticle surface. The growth mechanism and dopant distribution were found to be dependent on the nature of the hydroxyl ion source. Optical analysis revealed a distinct absorption peak in the range of 200—350 nm, making these nanoparticles suitable for UVB filter applications. The nanoparticles exhibited a palette of bluish-green hues, with colorimetric properties dependent on synthesis conditions. The Cr-HAp nanoparticles demonstrated great stability as Pickering emulsions, and exhibited enhanced functionality upon vitamin A encapsulation. These findings highlight the potential of Cr-HAp nanoparticles in advanced materials for cosmetics.

基于掺铬羟基磷灰石纳米颗粒的绿色酸洗乳剂：稳定剂的生产、稳定性研究和维生素A包封

研究了合成条件对铬掺杂羟基磷灰石抗紫外线纳米粒子（Cr-HAp）结构、形态和光学性能的影响。采用共沉淀法和水热法制备了具有细长单晶针状结构的Cr-HAp纳米颗粒。量子化学计算提供了定向附着过程和离子与纳米颗粒表面相互作用的见解。发现羟基离子源的性质决定了掺杂物的生长机制和分布。光学分析显示，在200-350 nm范围内有一个明显的吸收峰，使这些纳米颗粒适合于UVB过滤器的应用。纳米颗粒呈现出蓝绿色色调，其比色特性取决于合成条件。Cr-HAp纳米颗粒在皮克林乳液中表现出很强的稳定性，并且在维生素A包封后表现出增强的功能。这些发现突出了Cr-HAp纳米颗粒在化妆品高级材料中的潜力。

期刊介绍： The aim of the journal is to provide a respectful outlet for ''sound science'' papers in all research areas on surfaces and interfaces. We define sound science papers as papers that describe new and well-executed research, but that do not necessarily provide brand new insights or are merely a description of research results. Surfaces and Interfaces publishes research papers in all fields of surface science which may not always find the right home on first submission to our Elsevier sister journals (Applied Surface, Surface and Coatings Technology, Thin Solid Films)
