通过光致发光（PL）光谱研究了氢氧化镉层状Q-CdS团簇与多核苷酸之间的内在相互作用。对于平均直径为40埃且发光最大值在480 nm附近的半导体簇，可以通过添加多核苷酸如来自大肠杆菌的脱氧核糖核酸（DNA）来实现这种发射的猝灭。大肠杆菌或聚腺苷酸（poly[A]）
The intrinsic interaction between cadmium hydroxide-layered Q-CdS clusters and polynucleotides has been examined via photoluminescence (PL) spectroscopy. For semiconductor clusters of 40-A average diameter and a narrow luminescence maximum near 480 nm, quenching of this emission can be accomplished by the addition of polynucleotides such as deoxyribonucleic acid (DNA) from E. coli or polyadenylic acid (poly[A])
