The tetragonal LaOF:Eu3+ nanoparticles have been successfully synthesized by three different methods including hydrothermal, solvothermal and chemical precipitation methods. Strong red fluorescence emissions were observed by exciting the samples with 532 nm laser. Under the proper conditions, the sample synthesized via chemical precipitation method presented the strongest fluorescence emission. It is found that the particle size, surface modification, crystal structure and local environment could be adjusted with different preparation processes.
