Abstract The NO 3 – ‐type Eu 3+ ‐doped layered gadolinium hydroxide (NO 3 –LGdH:Eu) was prepared by a developed homogeneous precipitation method through hexamethylenetetramine (HMT) hydrolysis with hydrothermal treatment. Two amino acid anions, phenylalanine (Phe) and tyrosine (Tyr), were intercalated into LGdH:Eu to form composites Phe–LGdH:Eu and Tyr–LGdH:Eu. Photoluminescence studies show that the incorporation of Phe and Tyr into the host layer can sharply quench the Eu 3+ luminescence. This simple method is expected to be applied in biological systems for detecting amino acids.
