The composition of erbium-doped yttrium aluminate ceramics was analyzed by means of confocal luminescence spectroscopy, EDX, and X-ray diffraction. A well-defined linear correlation was found between a proposed estimator computed from the luminescence spectrum and the proportion of ceramic phases coexisting in different samples. This result shows the feasibility of using erbium luminescence spectroscopy to perform a quantitative determination of different phases of yttrium aluminates within a micrometric region in nanograined ceramics. •The composition of erbium-doped yttrium aluminate ceramics was analyzed by means of photoluminescence and X-ray diffraction.•A linear correlation was found between a proposed luminescence estimator and the proportion of coexisting phases.•This result shows the feasibility of this spectroscopy to perform quantitative analysis of ceramic composition.
