A new technique for analysis of "Ligand partial pressure - Temperature" diagram has been developed for the organometallic phosphor tris(8-hydroxyquinoline) M (M = Al, Ga, In). The detection of mono- and bivariant equilibriums within the p_8-Hq-T diagram has been done using simultaneous measurements of photoluminescence and reflection spectra of a condense phase under controlled p_8-Hq and T. Using preparations with the purity better than 99.999 wt% the corresponding p_8-Hq-T diagrams have been plotted in the temperature range from 350 K to the maximum melting temperatures of the compounds. The homogeneity ranges of different polymorphs have been determined. For the different polymorphs it have been demonstrated that changing the synthesis conditions within the homogeneity range of the phases resulted to the significant changes of the nonstoichiometry, chemical activities and electroluminescent properties of the OLED structures, prepared on the base of β-Mq₃.

对于有机金属磷光体三（8-羟基喹啉）M（M = Al，Ga，In），已经开发了一种用于分析“配体分压-温度”图的新技术。使用受控p _8-Hq和T的同时测量凝聚相的光致发光和反射光谱，已经完成了对p _8-Hq - T图内单变量和双变量平衡的检测。使用纯度高于99.999 wt％的制剂，相应的p _8-Hq - T在350 K至化合物的最高熔融温度范围内绘制了图表。已经确定了不同多晶型物的均质范围。对于不同晶型它已被证明相的均匀性范围内改变合成条件导致的非化学计量的OLED结构的显著变化，化学活动和电致发光特性，β-了Mq的基础上制备的₃。
