Systems and method for filtering emissions from scintillators are provided. One system includes a scintillator having a scintillator material portion formed from a base scintillator material. The scintillator also includes a photodetector and a filter portion, The filter portion includes a material blocking near-infrared (IR) emissions. The filter portion is disposed on a surface of one of the scintillator material portion or the photodetector, and wherein the scintillator material portion, the photodetector, and the filter portion are coupled together. The filter portion blocks the near-IR emissions from impinging on the photodetector.
