Evan G. Moore, Ebinazar B. Namdas, Shih‐Chun Lo and co‐workers (article number 1901350) discover a new class of solution processable organic semiconductor laser dyes with deep‐red emission. These dyes exhibit high photoluminescence quantum yields and low amplified spontaneous emission (ASE) thresholds. Their use of a mixed host of 1,3‐bis(N‐carbazolyl)benzene (mCP) and 2‐hydroxyphenylbenzothiazole (HBT) not only leads to efficient cascade energy transfer, but significantly enhances the photostability of the films thanks to much lower heat dissipation in the chromophores.

有机激光染料：大自然激发的海湾环状靛蓝衍生物的深红色激光发射和自发发射（高级光学材料2/2020）

Evan G. Moore，Ebinazar B. Namdas，Shih-Chun Lo及其同事（文章编号1901350）发现了一类新型的可溶液处理的深红色发射有机半导体激光染料。这些染料显示出高的光致发光量子产率和低的扩增自发发射（ASE）阈值。他们使用1,3-双（N-咔唑基）苯（mCP）和2-羟基苯基苯并噻唑（HBT）的混合基质不仅可以有效地级联能量转移，而且由于低得多的热量也大大提高了薄膜的光稳定性。消散在发色团中。
