In a groundbreaking discovery, a team of Russian scientists has developed a technology that enhances the visualization and accuracy of X-rays, crucial for both medical diagnostics and scientific research. This advancement, announced on October 3, 2024, by researchers from the Institute of General Physics of the Russian Academy of Sciences, promises to revolutionize how X-rays are utilized in various fields.
The researchers found that under conditions of microwave plasma—a mixture of methane and hydrogen heated to thousands of degrees—europium ions capture electrons, leading to a change in their luminescence. This phenomenon is vital for improving the efficiency of X-ray detectors. With the ability to fine-tune these detectors, medical professionals can more accurately identify diseases, while scientists can explore different materials with greater precision.
X-rays, which are pivotal in diagnosing illnesses and conducting scientific investigations, typically use radiation that is hundreds of thousands of times stronger than conventional X-ray machines. However, since X-rays themselves are invisible, directing them toward specific objects presents a challenge. This is where the new composite material, made of diamond embedded with europium and strontium nanoparticles, comes into play.
When exposed to X-rays, these nanoparticles begin to fluoresce, allowing for the detection of the radiation. The study revealed that the luminescence changes due to reactions between the nanoparticles and hydrogen in the plasma. By adjusting the temperature and processing time, scientists can customize the emission spectrum, paving the way for enhanced X-ray systems.
This innovative approach not only holds promise for improving medical imaging techniques but also opens new avenues for research in materials science, potentially leading to breakthroughs in various technological applications.
