Synthesis YPO4:Eu3+ Nanophosphor from Fungi

Abstract

Live fungi (zygo and asco) were cultivated and grown in an agar solution with a 2000 ppm concentration of Y3+ from YNO3 and a 20 ppm concentration of Eu3+ from EuNO3. When the fungi were grown to a good amount, they were collected, dried, and burnt at 1000°C for 2 h in air. X-ray diffraction, scanning electron microscopy, and optical spectroscopy experiments revealed that the product was nanophosphor YPO4:Eu3+ with a size of 100–200 nm.
