Dibenzoterrylene (DBT) molecules within a crystalline anthracene matrix show promise as quantum emitters for controlled, single photon production. We present the design and construction of a chamber in which we reproducibly grow doped anthracene crystals of optical quality that are several mm across and a few μm thick. We demonstrate control of the DBT concentration over the range 6-300 parts per trillion and show that these DBT molecules are stable single-photon emitters. We interpret our data with a simple model that provides some information on the vapour pressure of DBT.
在结晶蒽基质中的二苯并苝（DBT）分子有望成为用于可控单光子产生的量子发射器。我们展示了一个腔室的设计与构建，在该腔室中我们可重复生长出光学质量的掺杂蒽晶体，其尺寸为几毫米见方且厚度为几微米。我们证明了在万亿分之6至300的范围内对DBT浓度的控制，并表明这些DBT分子是稳定的单光子发射器。我们用一个简单模型来解释我们的数据，该模型提供了一些关于DBT蒸气压的信息。
