ABSTRACT A new cadmium complex is synthesized to investigate its stability and applicability for a luminescent device. The as-prepared Cd(Bpy)q sample is characterized by Fourier-transformed infra-red spectroscopy (FTIR), thermal gravimetric analyzer (TGA) and photoluminescence (PL). The prepared sample shows excellent thermal stability up to 380 °C. A maximum is observed at 240 nm in absorption spectra which is attributed to the pi-pi* transition. An organic-light-emitting diode (OLED) has been fabricated using this material. The fundamental structures of the device exhibit ITO/alpha-NPD/Cd(Bpy)q/BCP/Alq3/LiF/Al. The electroluminescence (EL) device emits bright green light with maximum luminescence 1683 cd/m2 at 20 V.

    ABSTRACT: The stability and applicability of new cadmium complex, Cdmq2, is investigated for electroluminescent device application. The Cdmq2 is characterised by different characterisation techniques. It shows excellent thermal stability up to 440 °C. A maximum is observed at 390 nm in absorption spectra which attributed to π - π* transition. Organic light emitting diode (OLED) has been fabricated using this material. The integral parts of the device were ITO/α-NPD/Cdmq2/BCP/Alq3/LiF/Al. Electroluminescence (EL) device emits yellowish green light with maximum luminescence 1185 cd/m2 at 23V.
