Assembling Ln(HPBA) (Ln = Eu or Tb, HPBA = N-(2-pyridinyl)benzoylacetamide) in the cavities of zeolite Y (ZY) via the "ship-in-a-bottle" strategy leads to the formation of novel luminescent composite, Ln(HPBA)@ZY, whose luminescence can be easily modulated by ammonia on the basis of the energy level variation of HPBA after deprotonation process. Additionally the bimetallic complex doping sample, EuTb(HPBA)@ZY, show great potential as self-referencing luminescent sensor for detecting low ammonia concentration of 10⁻0.25 wt%.

通过“瓶中船”策略将 Ln(HPBA)（Ln = Eu 或 Tb，HPBA = N-(2-吡啶基)苯甲酰基乙酰胺）组装到沸石 Y（ZY）的空腔中，形成了新型发光复合材料 Ln(HPBA)@ZY，其发光可以通过质子化后的 HPBA 能级变化很容易地通过氨来调节。此外，双金属配合物掺杂样品 EuTb(HPBA)@ZY，作为自基准发光传感器，在检测低浓度氨（10⁻0.25wt%）方面具有很大的潜力。
