Quantum dots have unique size-dependent properties and promising applications. However, their use in many applications remains hindered by mechanical, thermal, and chemical instability and the lack of viable quantum dot mass-production processes. Embedding quantum dots in matrices such as silica counteracts the instability challenges in some applications while preserving their unique properties and applicability. Here, we synthesize quantum dots of four different metal oxides embedded in a silica matrix in a one-step mass-production process using flame spray pyrolysis.

量子点具有独特的尺寸依赖性特性和广阔的应用前景。然而，它们在许多应用中的使用仍然受到机械、热和化学不稳定性以及缺乏可行的量子点大规模生产工艺的阻碍。将量子点嵌入二氧化硅等基质中，在某些应用中可抵消不稳定性挑战，同时保留其独特性能和适用性。在此，我们使用火焰喷雾热解在一步大规模生产过程中合成了嵌入二氧化硅基质中的四种不同金属氧化物的量子点。
