Electrochemiluminescence of a Di-Boron Complex, Perovskite and Carbon Quantum Dots
Abstract
The electrochemiluminescence (ECL) of three novel materials was explored in this thesis. A di-boron complex exhibiting crystallization-induced blue shift emission was detected utilizing photoluminescence. This phenomenon was successfully observed in the annihilation pathway, resulting in crystallization-induced blue shift ECL. The effects of coreactant and crystallization-induced enhancements were distinguished utilizing two testing systems. Undoped and Mn-doped CsPbCl3 perovskites were investigated, as the latter exhibits a dual emissive photoluminescence pathway due to host and dopant emission mechanics. It was discovered that the electrochemiluminescence of Mn-doped CsPbCl3 proceeds through a triplet-triplet annihilation pathway. Furthermore, the relaxation of the electrochemically generated Mn-doped CsPbCl3 excited state was proposed to relax through a dual emissive pathway (surface states and dopant emission). Finally, a new synthetic method was developed for a green wavelength emitting carbon quantum dots (CQDs) from glucose and phytic acid precursors. Preliminary testing shows promise of CQDs as ECL luminophores.
