Photoluminescence and phosphorescence emissions of solid-state phenazine films were investigated in steady-state experimental conditions. Important discrepancies were observed for blended films where a host optically inert matrix was introduced to disperse the probe molecules. A vibronic spin-orbit phosphorescent emission clearly appeared, while for the films solely composed by the probe molecules, the phosphorescence broadened and presented a structureless shape, shifted to longer wavelengths. Further Arrhenius behavior analysis on the photoluminescent and phosphorescent emissions on temperature, corroborated the direct and reverse intersystem crossing interplay between singlet and triplet states. Molecular aggregation is responsible for the deterioration of non-blended triazole films phosphorescence.

在稳态实验条件下研究了固态吩嗪薄膜的光致发光和磷光发射。观察到掺混膜的重要差异，在掺混膜中引入了主体光学惰性基质以分散探针分子。明显出现了电子自旋轨道磷光发射，而对于仅由探针分子组成的薄膜，磷光变宽并呈现出无结构的形状，移至更长的波长。进一步的阿累尼乌斯行为分析对温度下的光致发光和磷光发射，证实了单重态和三重态之间的正向和反向系统间交叉相互作用。分子聚集是非共混三唑膜磷光劣化的原因。
