Hybrid plasmonic nano-emitters based on the combination of quantum dot emitters (QD) and plasmonic nanoantennas open up new perspectives in the control of light. However, precise positioning of any active medium at the nanoscale constitutes a challenge. Here, we report on the optimal overlap of antenna’s near-field and active medium whose spatial distribution is controlled via a plasmon-triggered 2-photon polymerization of a photosensitive formulation containing QDs. Au nanoparticles of various geometries are considered. The response of these hybrid nano-emitters is shown to be highly sensitive to the light polarization. Different light emission states are evidenced by photoluminescence measurements. These states correspond to polarization-sensitive nanoscale overlap between the exciting local field and the active medium distribution. The decrease of the QD concentration within the monomer formulation allows trapping of a single quantum dot in the vicinity of the Au particle. The latter objects show polarization-dependent switching in the single-photon regime.

基于量子点发射器（QD）和等离子纳米天线的混合等离子纳米发射器为光的控制开辟了新的前景。然而，任何活性介质在纳米尺度上的精确定位构成了挑战。在这里，我们报告了天线的近场和活性介质的最佳重叠，其空间分布是通过包含QD的光敏配方的等离激子触发的2光子聚合来控制的。考虑了各种几何形状的金纳米颗粒。这些杂化纳米发射体的响应显示出对光偏振高度敏感。通过光致发光测量证明了不同的发光状态。这些状态对应于激发局部场和活性介质分布之间的偏振敏感纳米级重叠。单体配方中QD浓度的降低允许在Au颗粒附近捕获单个量子点。后面的对象显示了单光子状态下偏振相关的切换。
