    • Coated color-converting particles and associated devices, systems, and methods are disclosed herein. A coating of the coated color-converting particles can include, for example, a parylene, such as a fluorinated parylene (e.g., parylene AF-4). In particular embodiments, the coating can be configured to protect a color-converting material of a particle core of the coated color-converting particles from detrimental reactions. For example, the coating can prevent, slow, or otherwise inhibit detrimental reactions between the color-converting material and a matrix material or between the color-converting material and an environmental constituent that can diffuse through a matrix. In particular embodiments, the coated color-converting particles can be incorporated into a matrix (e.g., a generally optically transmissive matrix) to form a composite. The composite can be used, for example, with a radiation transducer. Methods associated with the coated color-converting particles can include, for example, separating coated color-converting particles having acceptable coatings from coated color-converting particles having unacceptable coatings using relative buoyancy.
    • 本文公开了涂覆的颜色转换颗粒及其相关设备,系统和方法。 涂覆的颜色转换颗粒的涂层可以包括例如聚对二甲苯如氟化聚对二甲苯(例如聚对二甲苯AF-4)。 在具体实施方案中,涂层可以被配置为保护涂覆的颜色转换颗粒的颗粒核心的颜色转换材料免受有害反应。 例如,涂层可以防止,减慢或以其他方式抑制颜色转换材料和基质材料之间或可以通过基质扩散的颜色转换材料和环境成分之间的有害反应。 在具体实施方案中,涂覆的颜色转换颗粒可以结合到基质(例如,通常为光学透射的基质)中以形成复合物。 复合材料可以用于例如辐射换能器。 与涂覆的颜色转换颗粒相关的方法可以包括例如使用相对浮力从具有不可接受的涂层的涂覆的颜色转换颗粒中分离具有可接受涂层的涂覆的颜色转换颗粒。
