I'm working on RVG sensors and need information about their scintillator films and I need information to know what the material of this film is made of.
I would appreciate it If you have experience in this field help and share with me
Thank you very much for posting an interesting technical question. Scintillating materials/scintillators are the materials capable of converting ionizing radiation to visible light. These materials are playing an essential role in X-ray imaging as well as X-ray detection. As stated by Michael Uebel generally CsI is used as scintillator in RVG sensor. However, other scintillating materials capable of detecting and imaging with X-ray include powder materials like Gd2O2S:Tb (typically known as P43 or Gadox) and Y3Al5O12 :Ce (known as P46), single crystalline materials i. e. yttrium-aluminim-garnet:Ce (Y3Al5O12:Ce, namely YAG:Ce) and lutetium-aluminum-garnet:Ce (Lu3Al5O12:Ce, namely LuAG:Ce) etc. Only few examples are mentioned here. For more examples please have a look at the following article. This article is available on RG, but only the abstract are there. However, you can have the full article by requesting the corresponding author. I do not have the working experience with the application of the materials mentioned in this article, so you can use these scintillating materials to design new RVG sensors as a test basis. Good luck with your research !

Dear Alireza, to my knowledge RVG (RadioVisioGraphy) sensors are mainly used in dentistry:

As already mentioned in the previous expert answers, cesium iodide is the most common scintillator material used in such devices. One of the most brilliant scintillators known is thallium-activated (thallium-doped) cesium iodide, CsI:Tl. For more information about this material please have a look at the following very interesting article:
Multiple doping of CsI:Tl crystals and its effect on afterglow
Article Multiple doping of CsI : Tl crystals and its effect on afterglow
Various other articles related to CsI and CsI:Tl have been posted on RG.
Hi Dr Alireza Norouzi . They are made of inorganic materials, and are usually an alkali halide salt, such as sodium iodide (NaI) or cesium iodide (CsI). https://www.nuclear-power.com/nuclear-engineering/radiation-detection/scintillation-counter-scintillation-detector/scintillation-materials-types-of-scintillators/
