Photoluminescence : la mati\u00e8re comme cataliseur lumineux La structure \u00e9tudi\u00e9e est constitu\u00e9e d\u2019un mat\u00e9riau photoluminescent. Sous exposition OPPH, elle capte, conserve et restitue la lumi\u00e8re avec un l\u00e9ger d\u00e9calage, r\u00e9v\u00e9lant les ph\u00e9nom\u00e8nes internes d\u2019excitation mol\u00e9culaire. Ce ph\u00e9nom\u00e8ne, purement mat\u00e9riel, donne pourtant l\u2019impression d\u2019une \u00e9nergie vitale\u00a0 non pas celle du vivant, mais celle du mouvement intrins\u00e8que de la mati\u00e8re. La lumi\u00e8re n\u2019y figure pas la vie : elle manifeste la complexit\u00e9 du r\u00e9el, son \u00e9quilibre entre absorption et \u00e9mission.L\u2019eau : une mati\u00e8re du paradoxe \u00a0Explorer l\u2019eau, c\u2019est s\u2019approcher d\u2019un paradoxe : une substance fluide et transparente, \u00a0 \u00a0 mais d\u2019une architecture invisible, complexe et changeante. \u00a0 \u00a0 \u00c0 travers cette approche, l\u2019eau n\u2019est pas \u00e9tudi\u00e9e comme une m\u00e9taphore du vivant, \u00a0 \u00a0 mais comme une\u00a0mati\u00e8re premi\u00e8re de la perception, \u00a0 \u00a0 un champ d\u2019interf\u00e9rences entre densit\u00e9 et lumi\u00e8re, onde et surface. \u00a0 \u00a0 C\u2019est cette dimension que la photographie tente ici de r\u00e9v\u00e9ler\u00a0 \u00a0 \u00a0 non pas la vie de l\u2019eau, mais la vie de sa mati\u00e8re. \u00a0Une recherche entre art et science Cette \u00e9tude n\u2019appartient ni enti\u00e8rement \u00e0 la science ni \u00e0 l\u2019art, mais \u00e0 un espace partag\u00e9 entre les deux.
