A new technique for the analysis of p_8-Hq–T diagrams has been developed for the metal–organic phosphor tris(8-hydroxyquinoline)gallium. The detection of mono- and bivariant equilibria within the p_8-Hq–T diagram was done using simultaneous measurements of the photoluminescence and reflection spectra of the condensed phase under controlled p_8-Hq pressure and temperature. Using preparations with purity better 99.9988 wt%, the S_i-Gaq3S_j-Gaq3V and S_i-Gaq3LV equilibria were studied and the corresponding p_8-Hq–T diagram was plotted in the 408–665 K temperature range. For the α-Gaq₃, it was demonstrated that changing the synthesis conditions within the homogeneity range of the phase resulted in change in the cell volume, chemical activity and electrical properties of crystalline preparation and thin layers deposited due to it.
