The quantum confinement of Rydberg excitons is an important step towards exploiting their large nonlinearities for quantum applications. We observe Rydberg excitons in natural nanoparticles of Cu2O. We resolve up to the principal quantum number n=12 in a bulk Cu2O crystal and up to n=6 in nanoparticles extracted from the same crystal. The exciton transitions in nanoparticles are broadened and their oscillator strengths decrease as n4 compared to those in the bulk (decreasing as n3). We explain our results by including the effect of quantum confinement of exciton states in the nanoparticles. Our results provide an understanding of the physics of Cu2O Rydberg excitons in confined dimensions.

Cu2Onanoparticles中的量子限制里德堡激子

里德堡激子的量子限制是将其大非线性用于量子应用的重要一步。我们在天然纳米粒子中观察到里德堡激子2. 我们解析到主量子数n=12 大量 2 水晶和高达 n=6在从同一晶体中提取的纳米颗粒中。纳米粒子中的激子跃迁变宽,它们的振子强度随着n-4 与大部分相比(减少为 n-3)。我们通过包括纳米粒子中激子态的量子限制效应来解释我们的结果。我们的结果提供了对物理学的理解2 受限维度中的里德堡激子。
