“…Although inorganic LEDs based on III-V semiconductors such as GaN and InGaN have made semiconductor solid state lighting popular, accompanied with the significant saving of energy, the high-temperature, expensive vacuum-based manufacturing process employed to fabricate these semiconductors restricts their widespread application. The substitutes of inorganic LEDs contain organic light emitting diodes (OLEDs) [1][2][3][4][5][6][7][8][9][10][11][12][13][14], quantum dot light emitting diodes (QLEDs) [15][16][17] and perovskite light emitting diodes (PeLEDs) [18][19][20][21][22][23][24][25], which take advantage of the high photoluminescence quantum efficiency (PLQE), solution processability, good purity and tunability of color. For these new types of LEDs, high-efficiency and stable devices are still the objectives of research works.…”

Light-emitting diodes (LEDs) are considered to be the most promising energy-saving technology for future lighting and display. Two-dimensional (2D) materials, a class of materials comprised of monolayer or few layers of atoms (or unit cells), have attracted much attention in recent years, due to their unique physical and chemical properties. Here, we summarize the recent advances on the applications of 2D materials for improving the performance of LEDs, including organic light emitting diodes (OLEDs), quantum dot light emitting diodes (QLEDs) and perovskite light emitting diodes (PeLEDs), using organic films, quantum dots and perovskite films as emission layers (EMLs), respectively. Two dimensional materials, including graphene and its derivatives and transition metal dichalcogenides (TMDs), can be employed as interlayers and dopant in composite functional layers for high-efficiency LEDs, suggesting the extensive application in LEDs. The functions of 2D materials used in LEDs include the improved work function, effective electron blocking, suppressed exciton quenching and reduced surface roughness. The potential application of 2D materials in PeLEDs is also presented and analyzed.

“…18,19 In addition, WLEDs with inorganic phosphors tend to have low colour rendering capability due to the weak green and red emission. 20 Finally, the device performance is further hindered due to self-absorption which causes photoluminescence quenching in inorganic phosphors. 21 By comparison, organic materials used as the emissive layers in organic light-emitting diodes (OLEDs) possess distinct characteristics such as low manufacturing costs, ease of synthesis and colour tuning of emission, together with mechanical flexibility.…”
