    Resumen:
    The performance of YuGdwVO4 microcrystals with different atomic concentrations of Y3+ and Gd3+ ions, co-doped Er3+-Yb3+, as thermometers, exploiting two different calculation methods based on the fluorescence intensity ratio is investigated in the non-saturation regime. At a low excitation power density of 20 W cm−2, the thermometric parameters are approximately the same for all the analyzed sensors. Whereas for an excitation power density of 155 W cm−2, they are widely different all along the 303–513 K temperature range of study. Such as an increase on the Gd3+ ion concentration in the microcrystals induces a lattice expansion that can result in the decreasing of the lattice field surrounding the Er3+ ions and then it could enhance greatly the thermometric performances. For both calculation methods, it has been demonstrated that the ∆EFIR (fitted from the FIR curves) and the ∆ETS (determined using the TeSen Calculator program) values are lower than the ∆E` experimental (fitted from the emission spectra measured at room temperature), whenever the sample is heated and then the thermometric parameters are less competitive.
