Complexul a fost caracterizat prin spectroscopia de fotoluminescență și spectroscopia în infraroșu. Spectrele de fotoluminescență ale complexului reprezintă benzi de emisie puternice asociate cu tranzițiile 5D0→7Fj (j=0-4). Caracterul despicării benzilor de emisie, cât şi timpul de relaxare al luminescenței indică prezența a cel puțin două site-uri diferite ale ionului Eu3+ în mediu cu simetrie redusă. A fost determinat randamentul cuantic absolut al complexului de 49,2%.
