| Popis: | Mechanoluminescence materials, characterized with non-thermal light emission in response to mechanical stimuli, can have many applications in direct conversion of mechanical energy into light energy. The aim of this study was to develop wet chemistry approaches for the synthesis of the finest ceramic powders of barium calcium titanate for the use in the production of a mechanoluminescent detector. Wet chemistry route allows the control of the particle size of ceramic materials up to several nanometers. For the first time luminescence was recorded in Ba0.9Ca0.1TiO3 ceramics despite reports that light emission in BCT is possibly only over 23% of calcium content. The resulting ceramics showed high relative density, reasonable ferro and dielectric properties, and red light emission can be observed with the naked eye. |
