1：Experimental Design and Method Selection:

The study uses the 'ship-in-a-bottle' method to encapsulate Ln3+ complexes (Ln = Eu or Tb) within zeolite Y cavities. This involves ion-exchange to prepare Ln3+-exchanged ZY, followed by complex formation with the ligand HPBA. The rationale is to leverage the acidic microenvironment of zeolite Y and the deprotonation of HPBA by ammonia to modulate luminescence.

2：Sample Selection and Data Sources:

Samples include Eu(HPBAn)@ZY, Tb(HPBAn)@ZY, and Eu0.5Tb0.5(HPBAn)@ZY. Zeolite Y is obtained from Sigma-Aldrich, and lanthanide salts and ligands are purchased from chemical suppliers. Data sources include luminescence spectra, XRD, SEM, EDX, FT-IR, and elemental analysis.

3：5Tb5(HPBAn)@ZY. Zeolite Y is obtained from Sigma-Aldrich, and lanthanide salts and ligands are purchased from chemical suppliers. Data sources include luminescence spectra, XRD, SEM, EDX, FT-IR, and elemental analysis. List of Experimental Equipment and Materials:

3. List of Experimental Equipment and Materials: Equipment includes a Vector 22 FT-IR spectrophotometer (Bruker), NMR system VX300 (Varian), Elementar Vario EI elemental analyzer, S-4300 FE-SEM (Hitachi), Bruker D8 diffractometer, and FS920P near-infrared spectrometer (Edinburgh Instruments) with a xenon lamp and photomultiplier tube. Materials include zeolite Y, EuCl3·6H2O, TbCl3·6H2O, HPBA ligand, and solvents.

4：Experimental Procedures and Operational Workflow:

Steps involve synthesizing HPBA ligand, preparing Ln3+-exchanged ZY via ion-exchange in ethanol, grinding with HPBA to form complexes, washing and drying. For ammonia exposure, samples are placed in sealed containers with aqueous ammonia vapors for 1 hour, followed by luminescence measurement.

5：Data Analysis Methods:

Luminescence spectra are analyzed to measure emission intensities and ratios (e.g., IEu/ITb). Data is fitted exponentially to establish relationships with ammonia concentration. Statistical analysis includes R-squared values for curve fitting.
