EXperiment1-Nanoparticle and OLEDs

• Objective: – to see the effect of nanoparticles coated on glass side of

substrate:

-change in the spectrum -change in the max intensity

• Method:-2 samples with nanoparticles (1&2)-2 samples without nanoparticle (reference samples)

( 3&4)OLED structure: ITO/CUPC/TPD/Alq3/Al

With nanoparticles Without nanoparticles1

Conclusion

• There seems to be no change in the wavelegth corresponding to the peak intensity

• The intensity of sample2 & 1 (with nanopartilces) is maximum of all , but it is difficult to say the change is significant.

• So i prefer to repeat the expérimente , with better coating of nanoparticles

• & I will send the IVL measurment results
