BuEh-PPV

Figure 10-9. Emission spectra for a 210 nm thick film of BuEH-PPV spin-coalcd onto a glass substrate for different excitation pulse energies. Optical excitation was accomplished with laser pulses of duration 10 ns (according to Ref. [37]).

Among the polymers PPV, MEH-PPV, BuEH-PPV, DOO-PPV and Si-PPV have been used to fabricate LEDs and optically pumped lasers. Most of these polymers emit the light in the yellowish-green to red regions of the spectrum [73],... 

Figure VII-8 Normalized emission spectra taken from a 150 nm thick film of BuEH-PPV on silicon dioxide pumped at intensities of 0.34 kW/cm (dotted line), 0.61 kW/cm (dashed line) and 5.2 kW/cm (solid line). The dimensions of the pump stripe were 200 pm by 2 mm and light was collected from the end of the stripe. (Taken from ref. 306)...
