Description
Technical Field
The invention relates to the technical field of testing, in particular to an up-conversion real-time reversible dynamic synchronous testing device for a ferroelectric film material.
Background
With the gradual exhaustion of fossil fuels and the continuous deterioration of the environment caused by the exhaustion of fossil fuels, researchers pay more attention to the development and application of solar energy. As one of important applications of solar energy, most semiconductor materials used in the solar cell do not respond in the near infrared due to large forbidden band width, which greatly hinders the improvement of the efficiency of the solar cell. To address this problem, researchers at home and abroad have tried to use rare earth ion doped up-conversion optical properties to convert near infrared light into visible light and then to absorb the visible light by semiconductor materials. So far there has been an increasing search around this idea.
The rare earth ions in the up-conversion ferroelectric film material are tightly combined with the semiconductor, so that the up-conversion ferroelectric film material is more efficient even if non-radiative energy transfer is carried out, and the non-radiative energy transfer is possible, thereby being more beneficial to the rare earth ions to transfer the energy to the semiconductor material.
Because the mechanism of regulating the up-conversion luminescence property by the ferroelectric property is not clear, the mechanism of regulating the up-conversion luminescence property by the ferroelectric property is better cleared. A ferroelectric up-conversion synchronization device is urgently needed to research the ferroelectric property, regulate up-conversion luminescence and enhance up-conversion efficiency.
Therefore, the performance research for the up-conversion ferroelectric thin film material is crucial. For the performance of the up-conversion ferroelectric thin film material, a tool capable of performing performance test on it is required.
