Phosphors constitute the most important component of organic light emitting diodes (OLEDs), therefore, there has been continuous development in this field. Molecular hybrid phosphors are basically transition metal complexes that are formed by complexation of heavy metal ion with suitable ligand system. The cyclometalated transition metal complexes constitute the major chunk of molecular hybrid phosphors. This chapter covers molecular hybrid phosphors based on complexes of heavy metals such as gold, iridium, platinum, rhodium and ruthenium.
