TADF is the expansion of thermally activated Delayed fluorescence process in OLED devices. It displays emissions of light in colors from green to deep-red through Intersystem crossing from the singlet to the triplet excitons,a world first.
OLEDS is the organic light emitting diodes has greatly advanced. OLEDS application such as smart phones,lightning,and flat panel displays.It contain rare material such as Platinum and iridium because of their efficiency and stability. The cost is very high.
It is the recombinantion of electron and holes in the active material lead to the formation of various excited state such as singlet and triplet excitons
