研制了一种基于1，4-双(4-甲基苯乙烯基)苯(BSB-Me)单晶的双极型发光有源场效应晶体管(LE-OFET)。BSb-Me单晶的光致发光量子效率(Phi(PL))高达89+/-2%，而气相沉积的BSb-Me薄膜的光致发光量子效率(Phi(PL))仅为54+/-2%。基于BSb-Me单晶的场效应管具有连续的蓝色电致发光，实现了几乎相等的电子和空穴迁移率[约0.005 cm(2)/(V S)]，并具有不对称的金-钙接触。由于BSb-Me单晶可以实现光放大，基于BSIB-Me的双极LO-OFET是未来电驱动有机蓝光固体激光器的一种很有前途的候选者。(C)2008年日本应用物理学会。
An ambipolar light-emitting organic field-effect transistor (LE-OFET) based on a 1,4-Bis(4-methylstyryl)benzene (BSB-Me) single crystal was developed. The BSB-Me single crystal has very high photoluminescence quantum efficiency (phi(PL)) of 89 +/- 2%, while phi(PL) of the BSB-Me vapor-deposited film is limited to a much lower value of 54 +/- 2%. Ambipolar operation with successive blue electroluminescence from the FETs based on the BSB-Me single crystals was demonstrated by realizing nearly equal electron and hole mobilities [about 0.005 cm(2)/(V s)] with asymmetric gold-calcium contacts. Since BSB-Me single crystals can perform light amplification, the BSIB-Me-based ambipolar LE-OFET is a promising candidate for future electrically driven organic blue-emitting solid-state lasers.
