Gf. Desa et al., A NOVEL FLUORINATED EU(III) BETA-DIKETONE COMPLEX AS THIN-FILM FOR OPTICAL-DEVICE APPLICATIONS, Optical materials, 11(1), 1998, pp. 23-28
We discuss the synthesis and spectroscopic characteristics of a thin f
ilm (similar to 3(3-90 nm) based on lanthanide europium (III) complexe
s as the emitter layers, to shift the UV portion of light spectrum int
o the visible region. The complex presents high quantum efficiency (si
milar to 65%), is highly volatile and thermodynamically stable. In add
ition, the thin him is used as an alternative antireflection coating o
n a silicon solar cell, allowing for an improvement of about 21% on ce
ll efficiency. The high absorption and luminescence properties in the
UV-visible region and its compatibility with device fabrication proces
ses make this material of great potential for use in advanced optical
device technologies. (C) 1998 Elsevier Science B.V. All rights reserve
