Carbon-dot (C-dot) liposome consisting of several thousands of C-dots shows interesting photoswitching properties. The water-dispersible C-dot liposome possesses intrinsic photoluminescence (PL) and is stable against salt and photoirradiation. The PL of C-dot liposome can be turned off and then on under photoirradiation over the wavelength regions of 510-540 nm and 365-420 nm, respectively. Like reported C-dots, the C-dot liposome emits various colors when excited at different wavelengths. Having great stability and high contrast, images of individual C-dot liposome have been recorded, showing negligible photoblinking. Through a simple photolithographic approach, micropatterns of C-dot liposomes emitting different colors have been fabricated.
由数千个碳点组成的碳点脂质体表现出有趣的光开关特性。这种水分散性的碳点脂质体具有固有光致发光（PL）特性，并且能够耐受盐和光照射。碳点脂质体的 PL 可以在分别为 510-540nm 和 365-420nm 的光照射下关闭和打开。与报道的碳点一样，当在不同波长下激发时，碳点脂质体发出各种颜色的光。由于具有良好的稳定性和高对比度，可以记录单个碳点脂质体的图像，显示出可忽略的光闪烁。通过简单的光刻方法，可以制备发射不同颜色的碳点脂质体的微图案。
