RESEARCH INTERESTS

We aim to design advanced optoelectronic deviceswithorganic or organic-inorganic hybrid materials, focusing on applications in radiation detection and energy generation. Current research orientations involve creating high - resolution radiation detectors to accurately identify different radiation types, high - performance photodetectors with enhanced sensitivity and fast response times, and designing functional encapsulants for high - performance optoelectronics, all with the goal of pushing the boundaries of optoelectronic device technology and contributing to progress in radiation detection and energy generation fields.
