title: Structure and Optimum Luminescence for Nearly Block-Like LaOCl:Eu3+ Nanoparticles.
abstract: In this work, we report a simple method for the synthesis of block-like Eu3+ doping LaOCl nanophosphors with different doping content. It was found that the average grain diameter of Eu3+ doping LaOCl samples decreased with increasing Eu3+ doping concentration. The lattice volume shrinked due to different response for different axial under high pressure that led to lower lattice symmetry of LaOCl:Eu3+. The emission of LaOCI:Eu3+ increased with the increasing Eu3+ concentration due to the lower local symmetry, which also led to a gradual reduction in lifetime.
