Synthesis and photometric properties of efficient white‐emitting phosphor of M‐AMG transition metal complexes for OLED applications

Abstract

Progression in lighting sources mainly depended on new, robust energy‐efficient diodes due to their advanced photometric properties. All organic light‐emitting sources are constant energy‐efficient devices and will be the light of the future. We explore the potential of transition metal complexes by focusing on cobalt(II), nickel(II), and copper (II) with aminoguanidine naphthoate as white phosphors in organic light‐emitting diodes (OLEDs). The phosphors synthesized at optimized temperature were characterized structurally and thermally by spectral, thermal, and diffraction techniques. The photophysical studies of the target compound in several organic solvents having divergent polarity were also studied, and the results were exhibited. Photometric properties of the complexes were studied using photoluminescence, CIE (Commission internationale de l'éclairage) chromaticity coordinates, correlated color temperature, color purity, Duv, and TLCI (Television Lighting Consistency Index) to verify the applicability of complexes as phosphors. Excellent luminescence property with a high coloring index for (Cu(2NA‐AMG‐2H2O)) opens the advanced avenue for light sources and serves as vital constituents for light‐emitting diodes.

Smart and intelligent optical materials for sensing applications

“…The results of this study indicated indirect damage to cell organelles apart from the sites of photosensitizer localization and led to cell death in PDT. Swathika and Natarajan [55] synthesized complexes of (Ni[2NA‐AMG‐2H 2 O]), (Co[2NA‐AMG‐2H 2 O]), and (Cu[2NA‐AMG‐2H 2 O]) for developing white phosphors. The results of this study suggested that Cu(2NA‐AMG‐2H 2 O) had outstanding optical properties with a high colouring index, which opened a new avenue for light sources.…”

Six polyoxotungstate-based transition metal compounds for electrochemical capacitor application and a comparative analysis of factors affecting capacitances

“…Consequently, scientists have been motivated to explore alternative candidates. Meanwhile, transition metal complexes, known for their high specific surface area, adjustable pore size and good thermal stability, have found extensive application prospects in magnetism, [29][30][31][32][33] catalysis, [34][35][36] luminescence, 34,37,38 electrochemical sensors, [39][40][41] etc. As a result, an encouraging strategy of incorporating POMs into transition metal complexes (TMCs) to build POM-based transition metal complexes (POM-TMCs) was put forward.…”
