Low thresholds for a nonconventional polymer blend-Amplified spontaneous emission and lasing in F8 sub(1-) sub(x):SY sub(x) system
A mixture of two polymer materials, poly (9,9-dioctylfluorene) (F8), and one of the poly(para-phenylenevinylene) derivatives, superyellow (SY) have been used to make F8 sub(1-) sub(x):SY sub(x) polymer blend system. Under a 3-5 ns pulsed-laser excitation, this system showed excellent optical propert...

| description | A mixture of two polymer materials, poly (9,9-dioctylfluorene) (F8), and one of the poly(para-phenylenevinylene) derivatives, superyellow (SY) have been used to make F8 sub(1-) sub(x):SY sub(x) polymer blend system. Under a 3-5 ns pulsed-laser excitation, this system showed excellent optical properties with low threshold values of approximately 14 mu J/cm super(2) and approximately 8 mu J/cm super(2) for amplified spontaneous emission and optically pumped lasing, respectively. The proposed system was also electroluminescent and an interesting candidate for future research on polymer injection lasers. J. Polym. Sci., Part B: Polym. Phys. 2016, 54, 15-21 A nonconventional polymer blend system, F8 sub(1-) sub(x):SY sub(x) based on poly(9,9-dioctylfluorene) (F8) and one of the poly(para-phenylenevinylene) derivatives, superyellow (SY), shows low thresholds for amplified spontaneous emission and optically pumped lasers. The blend system also shows excellent performance when used as an emissive layer in polymer LEDs. The combination of excellent optical and electro-optical properties of F8 sub(1-x):SY sub(x) make this system interesting for future research on advanced device architectures such as polymer injection lasing. |
