Resumo

New high efficiency luminescence films that convert UV radiation in a wavelength range of 220–410 nm into the europium ion luminescence are first obtained using a supramolecular diamond-containing complex of europium(III) with bathophenanthroline. The films allow the degree of radiation monochromaticity to be tuned at the main band of Eu3+ ions, centered at 615 nm. The excitation spectrum profile, as well as the half-width of the main emission band at 615 nm (a 5D07F2 transition) and the quantum yield values (in a range of ~0.3–0.8), is found to depend on the type of matrix material. The optical materials presented in the present work are promising candidates for the design of various light-emitting devices, such as screens, indicators, solar concentrators, organic LEDs, and laser media.
