Recent Progress in Blue-Emitting Semiconductor Nanocrystal Quantum Dots for Display Applications

초록

Solution-processable semiconductor nanocrystal quantum dots possess remarkable optical characteristics, including high photoluminescence quantum yield, narrow photoluminescence linewidth, and size-dependent color tunability. Three primary colors, which are red, green, and blue, are essential for realization of electroluminescent display utilizing quantum dots. While extensive research has been conducted on red- and green-emitting quantum dots, the development of blue-emitting quantum dots lags behind other primary color materials. This comprehensive review provides an overview of the progress in the synthesis of various types of blue-emitting quantum dots and their device applications. Furthermore, perspectives on further advancement of blue-emitting quantum dots to meet the requirements for commercially viable electroluminescent displays is discussed. © The Author(s), under exclusive licence to Korean Institute of Chemical Engineers, Seoul, Korea 2024.
