A Review on Perovskites based nanocrystals as potential ECL emitter: Challenges and Future Opportunities

Abstract

Halide perovskites have emerged as a promising new generation of highly luminescent and rapidly developing class of materials with applications in several fields of optoelectronics, lasers, light emitting diodes (LEDs), and photovoltaics. Even though the Electrochemiluminescence (ECL) research start at 1964 and lot of organic, inorganic, nanostructured semiconductor, quantum dots etc., have been used as a luminophores, only Perovskite based semiconductor nanocrystals (PeNCs) has been utilized as a luminophore on 2016 onwards. This is because of limitation of stability of PcNCs in both aqueous and non-aqueous media. This juvenility in research can be overcome by tactical planning with the aid of comprehensive review. Halide perovskites are intriguing materials of interest because they are crystalline semiconductors that can be made at ambient temperature. In this review, we introduced ECL and its reaction mechanism of halide perovskites, where the rational design of synthetic methodology of perovskite plays a significant role in producing ECL are systematically discussed. Finally, we have summarized the ECL applications of halide perovskites and addressed the scope of future perspectives in improving the stability of ECL and its usefulness in bioanalytical and LED device based applications
