Phosphor thermometry is a niche method used in semiconductor manufacturing, biomedical applications, aerospace and more. It relies on the relationship between phosphorescent emission and temperature. Phosphors are a ceramic material that have a powder form as synthesized. The form of the phosphor impacts the intensity of the phosphorescent emission. Therefore, both the quality of the phosphor and the form it is used in, contribute to the accuracy and precision of phosphor thermometry. Synthesis of phosphors is a mature science. However, there is less knowledge on optimizing the form of the phosphor for high efficiency emission. In addition, there is limited work on combining phosphors for an improved emission spectra. This work focuses on sintering two phosphors, manganese dopped magnesium flurogermanate (MFG) and chromium dopped yttrium aluminum garnet (Cr:YAG). A water based slurry is doctor bladed onto a silicon wafer using a Kapton stencil to pattern the two phosphors side by side. After atmospheric sintering at 1200 C for two hours, the dual phosphor targets were characterized with phosphorescent spectroscopy and XRD. A combined phosphorescent signal was identified, but there was a reduction in emission intensity when compared to the raw powders. The combined signal is tested over a temperature range from -90 C to 450 C, demonstrating a wider range than each phosphor individually. Lastly the new spectrum shows the MFG  peak increasing with temperature while the Cr:YAG decreases. This spectral shifting is useful for a ratio method thermography.
