Developing green-emitting InP quantum dot light-emitting diodes (QLED) is lagging behind their red and green counterparts. Here, green InP quantum dots are prepared and incorporated into a QLED so to promote hole transport and reduce electron mobility, resulting in a maximum quantum efficiency of 16.3 %.
