我们在超流氦中用脉冲激光烧蚀法制备了硒化镉纳米粒子。所制备的纳米粒子表现出光致发光闪烁和清晰的蓝移发射，其线宽几乎等于均匀线宽。这些结果表明，我们的方法可以直接在超流氦中制备具有尖锐共振的量子点，使进一步实现共振光学操纵和低温系统中的光捕获。
We fabricated cadmium selenide nanoparticles using a pulsed laser-ablation scheme in superfluid helium. The fabricated nanoparticles showed photoluminescence blinking and a clear blueshifted emission whose linewidth was nearly equal to the homogeneous linewidth. These results demonstrate that our method can prepare quantum dots with a sharp resonance directly in superfluid helium, enabling the further implementation of resonant optical manipulation and optical trapping in cryogenic systems.
