The project is synthesis sintering and characterization of sesquioxides like YAG and yttrium oxide ceramics, particularly in the field of advance ceramics. YAG and Y2O3 is known for its excellent chemical stability, high melting point, thermal conductivity, and transparency in a wide spectral range. The traditional method of growing single crystals of Y2O3 faces challenges due to its high melting point, so polycrystalline transparent ceramics (PTCs) are used as an alternative, offering advantages such as easy fabrication and the ability to create complex structures. To lower the sintering temperature sesquioxides could be doped with sintering additives in a limited quantity so as not interfere with basic properties of sesquioxides. To enhance and observe altering the physical and chemical properties sesquioxides could be doped with Rare earth elements (REEs) can be doped. The project is about the development and compilation of various studies that focus on doping Y2O3 with REEs like erbium (Er3+), ytterbium (Yb3+), samarium (Sm3+), and europium (Eu3+), which significantly affect the characteristics of the material.
