\u201cA scintillator is a material capable of absorbing ionizing radiation \u2014 invisible and highly dangerous to humans \u2014 and converting it into light. In essence, it acts as an optical warning signal,\u201d explains Dr Makowski.
\u201cWe do not need to be near a nuclear plant to encounter ionizing radiation. With today\u2019s rapid technological progress, it appears in many settings \u2014 medical diagnostics, industry, and even space research.\u201d<\/p>

Scientists are searching for scintillation materials that are both ultra-fast and ultra-efficient. However, producing such materials remains extremely costly. One cubic centimetre of lanthanum bromide, commonly used in PET scanners, costs around \u20ac1,000.
\u201cWe decided to explore alternative approaches, specifically the use of photonic techniques to improve scintillator performance,\u201d says Dr Makowski. \u201cA key factor here is the Purcell effect, which increases the amount of light emitted by the material. When a molecule is excited, it releases energy \u2014 and by placing metal nanoparticles near the emitter, we can increase the probability that this energy will be released as light, and shorten the emission time. Crucially, the molecules and nanoparticles must not touch, as direct contact suppresses emission.\u201d<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

Until now, research on the Purcell effect has focused primarily on thin-film materials, limiting sample thickness. The innovative approach described in Advanced Materials<\/em> involves embedding perovskite nanocrystals and metallic nanoparticles together within a polymer matrix.
\u201cThis creates multiple local \u2018hot spots\u2019 of the Purcell effect. As a result, we are no longer constrained by sample thickness \u2014 our imagination becomes the only limit,\u201d emphasises Dr Makowski.
\u201cThis is a breakthrough, because we demonstrated that the Purcell effect can operate effectively in bulk materials. By harnessing it, we can enhance gamma-ray-induced scintillation. In the future, this may lead to cheaper and more efficient PET imaging, improved radioactive contamination detection, and new applications in space research.\u201d<\/p>

The Photonic Materials Research Group, led by Dr M. Danang Birowosuto, specialises in the growth and characterization of perovskite materials and in leveraging photonic phenomena to improve their performance. Current work focuses on achieving similar effects in lead-free materials. The researchers hope their findings will pave the way for broader practical applications.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
