respectively. All the complexes exhibit emissions peaked from 482 nm to 503 nm in solid state

respectively. By using these complexes solid powder as emitters

the light emitting diodes with the blue GaN material as substrate were prepared. The CIE color coordinates are in blue-green and yellow-green regions for the LED based on all the complexes. The maximum light emitting efficiency value for (ftfmppy)
