Fig. 2From: Synthesis of europium-doped VSOP, customized enhancer solution and improved microscopy fluorescence methodology for unambiguous histological detectionQuantification of Eu fluorescence. Eu fluorescence signal intensity increased linearly with increasing Eu concentration with both enhancer solutions. Therefore, both systems are suitable for quantitative detection of Eu3+ in solutions with neutral pH (n = 5).
