水凝胶由CdSe/CdS种子纳米棒构建块通过添加过氧化氢制成，并通过超临界干燥转化为气凝胶。气凝胶比水凝胶和纳米颗粒溶液显示出更高的光致发光量子产率和更长的寿命。这种观察的模型推导。
Hydrogels are fabricated from CdSe/CdS seeded nanorod building blocks by the addition of hydrogen peroxide and converted to aerogels by supercritical drying. The aerogels show higher photoluminescence quantum yields and longer lifetimes than the hydrogels and the nanoparticle solutions. A model for this observation is derived.
