Abstract

Quantum dots (QDs) are semiconductor nanocrystals with superior quantum efficiency, narrow emission linewidths, and tunable bandgaps, making them valuable in optoelectronics. However, their commercialization is hindered by instability under stress and environmental concerns related to heavy metal leaching. To address these issues, advanced encapsulation strategies, particularly using inorganic glass matrices (silicate, phosphate, borate), are crucial. This review examines the structure-property relationships between these matrices and QD variants (perovskite, chalcogenide). It highlights how glass host engineering through network modifiers and phase separation control affects QD growth, defect passivation, and stability. Host-guest interactions at the glass-QD interface enhance photoluminescence quantum yield (15–40%), narrow emission linewidths, and improve thermal quenching resistance (30–50% efficiency retention at 150 °C). These advancements enable emerging applications in solid-state lighting, mini-LED backlights, and X-ray detectors. This analysis provides insights into glass-mediated QD engineering and paves the way for eco-friendly photonic materials.

玻璃基质中量子点的原位生长：先进光学材料的新范例

量子点（QDs）是一种半导体纳米晶体，具有优异的量子效率、窄的发射线宽和可调谐的带隙，使其在光电子学中具有重要价值。然而，它们的商业化受到压力下的不稳定性和与重金属浸出有关的环境问题的阻碍。为了解决这些问题，先进的封装策略，特别是使用无机玻璃基质（硅酸盐、磷酸盐、硼酸盐）至关重要。本文综述了这些基质与QD变体（钙钛矿、硫系化物）之间的结构-性质关系。它强调了通过网络改性剂和相分离控制的玻璃宿主工程如何影响量子点生长，缺陷钝化和稳定性。在玻璃- qd界面的主客体相互作用增强了光致发光量子产率（15-40%），窄发射线宽，并提高了热猝灭性（在150°C下效率保持在30-50%）。这些进步使固态照明，微型led背光和x射线探测器的新兴应用成为可能。这一分析为玻璃介导的量子点工程提供了见解，并为环保光子材料铺平了道路。
