Compared with red and green emitters in organic light-emitting devices (OLEDs) ,it is much more difficult to develop blue emitters with matching performances due to the opposing requirements for optic
Phosphorescent iridium (Ⅲ) complexes have attracted wide attention as a result of their advantageousphotophysical properties,such as high sensitivity of emission properties to changes in the localenv
We developed a new sequential layer-by-layer deposition method for fabricating organometal halide perovskite thin films.
General studies believed that organometal halide perovskite form type II P-N junctions with fullerene derivatives (C60 or PCBM) ,which provide sufficient driving force for exciton dissociation.
Transition metal complexes have been widely used as light-emitting and photon-absorbing materials in optoelectronic devices with diverse applications.While these complexes have been intensively studie
