Cap in hand: Ricinoleic acid (RA) replaces oleic acid as capping ligand in the synthesis of upconverting nanocrystals in the size range of 10 nm. The presence of hydroxyl groups near the double bond in RA is advantageous in hydroxylation of the bond, and the size of the nanocrystals is preserved. The small size, high water dispersibility, and strong upconversion from the nanocrystals could be utilized in sensing and bioimaging applications.
蓖麻油酸（RA）在合成尺寸范围为10纳米的上转换纳米晶体时取代油酸作为封端配体。RA中双键附近的羟基有利于该键的羟基化，并且纳米晶体的尺寸得以保持。纳米晶体的小尺寸、高水分散性和强上转换特性可用于传感和生物成像应用。
