To search of new latent fingerprints detector, 1,10-phenanthroline Eu(III) amines ligand complexes, [phenEu (N2H4)(H2O)4](ClO4)3 (2), [phenEu(N2H4)2(H2O)2](ClO4)3 (3), [phenEu(C2N3H9)(H2O)3](Cl)3 (4) and [phenEu (C4H13N3) (H2O)3](Cl)3 (5) by reaction of hydrazine, dimethylenetriamine, diethylenetriamine and 1,10- phenanthroline to fluorescence compound [phenEuCl3(H20)3](H2O)3 (1) were synthesized. For an example, the fluorescence spectrum of the complexe 2 is also pH dependent, where the fluorescence is ‘switched on’ at 360 nm, in pH region of 9-10, but the emission is quenched between pH 4-9. From the comparison results of fingerprints detectability between the complexes (1-5) and ninhydrin, latent fingerprints detectability of the complexe 5 showed 7 times better than ninhydrin.

새로운 잠재지문 현출제를 탐색하기 위하여 형광성 화합물, [phenEuCl3(H20)3](H2O)3 (1)에 hydrazine, dimethylenetriamine, diethylenetriamine 및 1,10-phenanthroline을 반응시켜 1,10-phenanthroline Eu(III) 아민류 리간드 착 화합물, [phenEu(N2H4)(H2O)4](ClO4)3 (2), [phenEu(N2H4)2(H2O)2](ClO4)3 (3), [phenEu(C2N3H9)(H2O)3](Cl)3 (4) 및 [phenEu(C4H13N3)(H2O)3](Cl)3 (5)를 각각 합성하였다. 한 예로, 착 화합물 2의형광 스팩트럼은 pH에 의존적이었고 pH 9-10 부근과 360 nm에서 형광을 방출하였으며 pH 4-9 사이에서는 형광방출이 소실되었다. 이들 착 화합물들(1-5)과 ninhydrin의 지문 현출능력을 비교한 결과, 착 화합물 5의 잠재지문 현출 능력이 ninhydrin보다 7배 이상 양호하였다.
