11. Many modern OLEDs incorporate a simple bilayer structure, consisting of a conductive layer and an emissive layer. 12. This happens closer to the emissive layer, because in organic semiconductors holes are generally more visible region. 13. TA measurements can also be used to predict non emissive states and dark states unlike time resolved photoluminescence. 14. In some cases, emissive power and absorptivity may be defined to depend on angle, as described below. 15. In 2012 the first inherently stretchable LEC using an elastomeric emissive material ( at room temperature ) was reported. 16. The black face of the cube is highly emissive , as indicated by the reddish color of the thermograph. 17. The quencher then returns to the ground state through emissive decay ( fluorescence ) or nonradiatively ( dark quenching ). 18. "' Emissive probes "'use an electrode heated either electrically or by the exposure to the plasma. 19. EFN is the electric field that exists between the electron emissive tip and the positively biased structure drawing the electrons out. 20. Kirchhoff's great insight was to recognize the universality and uniqueness of the function that describes the black body emissive power.
