摘要：

We discuss the synthesis and spectroscopic characteristics of a thin film (similar to 3(3-90 nm) based on lanthanide europium (III) complexes as the emitter layers, to shift the UV portion of light spectrum into the visible region. The complex presents high quantum efficiency (similar to 65%), is highly volatile and thermodynamically stable. In addition, the thin him is used as an alternative antireflection coating on a silicon solar cell, allowing for an improvement of about 21% on cell efficiency. The high absorption and luminescence properties in the UV-visible region and its compatibility with device fabrication processes make this material of great potential for use in advanced optical device technologies.
