The present investigation proposes the use of 2-(hydroxyl) quinoline lithium (Liq) in the form of an n-type doping agent to improve the accomplishment of white hybrid-OLED (WHOLEDs). One of the crucial factors for device applications is the improved electron injection and efficient balancing of holes & electrons in the emitting layer, which is achieved by doping the Liq in the tris(8-hydroxyquinolinato) aluminum (Alq3) layer. This investigation examines the optimal composition (liquid enthrallment and breadth) of the Alq3 : Liq n-type inebriate (intoxicate) electron injection layer (EIL) due to white hybrid-OLED (WHOLED) devices. In investigation involves correlate the current density and efficiency outcomes including those obtained using the traditional Alq3/LiF approach. To prevent exciton quenching, a inutility layer or interloper is often introduced in the midst of the emitting layer & the electron injection layer (EIL). This study examines the appropriate material and optimal thickness for the obstructing layer white small molecule organic light-emitting diode (SM-OLEDs) using of the 1,3,5-tris (N-phenylbenzimidazol-2-yl) benzene (TPBi) Stamp fetch technique. In Suggested Stamp fetch procedure offers a means to circumvent the intricacies associated with the vacuum deposit technology.
