| 英文摘要 | Organic solid-state lasers (OSSLs) are broadly tunable coherent sources, potentially compact, convenient, and manufactured at low costs. As compared with conventional organic materials, organic molecules with excited state intramolecular proton-transfer (ESIPT) process are excellent active laser medium candidates due to their inherent four-level system. This study demonstrates the effect of the polymorphism-dependent ESIPT on the OSSLs. It is found the alpha-phase crystals with a low photoluminescence quantum efficiency of approximate to 2% emit two components: the tautomer A emissions and the tautomer B emissions, which indicate the noncomplete ESIPT case. For comparison, the beta-phase crystals with moderate intramolecular hydrogen-bonding emitting near-infrared photoluminescence have all tautomer B emissions, which are of relatively high photoluminescence quantum efficiency (approximate to 15%) and are redshifted by an average of approximate to 250 nm from the corresponding absorptions. The complete ESIPT process of the beta-phase crystals contributes to the amplified spontaneous near-infrared emission (lambda approximate to 730 nm) with a low threshold of approximate to 1.86 mu J cm(-2). This work has provided the platform for the investigation of the ESIPT lasers, which contributes to the high-performance organic solidstate near-infrared laser devices. |
