Monolayers of a newly synthesized long-chain complex of europium(III)
and its mixtures with octadecane or arachidic acid were investigated.
Using the conventional LB and horizontal methods, the mixed monolayers
could be deposited on solid supports. For the complex in monolayer as
semblies, the emission probabilities from higher excited state D-5(1)
than D-5(0) were remarkably enhanced in comparison with those in the s
olution or crystalline.
