A novel approach was developed to study the relationship between DNA sequences and DNA‐templated silver nanoclusters (DNA‐Ag NCs) in detail by using an ordinary DNA strand as an example. Three kinds of Ag NCs are formed by using the DNA strand as a scaffold. By dividing the DNA template into several parts according to their different affinities to Ag + , it was found that the fluorescence properties of DNA‐Ag NCs are related to not only the sequences but also to the position of different parts in the template, which provides a more efficient approach to obtain DNA‐Ag NCs with required photoluminescence properties and may ultimately contribute to the targeted synthesis of DNA‐Ag NCs.
