title = "H-shaped oligofluorenes for highly air-stable and low-threshold non-doped deep blue lasing",
abstract = "H-shaped oligofluorenes as gain media exhibit excellent photo- (large robustness against oxidation) and thermal stabilities in ambient atmosphere for large σe and low-threshold (0.22 nJ pulse-1) deep blue distributed feedback (DFB) lasers. Their amplified spontaneous emission (ASE) thresholds increase less than 3-fold and the emission spectra exhibit almost no shift with film samples annealed up to 200 °C in open air.",
