The Pharaoh's snake experiment has been handed down for thousands of years, bringing a lot of Oriental mysteries. Its key technology is to establish a porous structure with expanded volume. Here, the Pharaoh's snake techniques have been used for producing rare earth-doped glass. The high-sodium precursor composed of SiO2-Na2CO3-P2O5-Er2O3 is prepared by the water-cooling method，which exhibits the phenomenon of Pharaoh's snake at 300℃ and forms fluffy Er-doped glass-sooting. Then the glass-sooting is crushed and further mixed with SiO2 thoroughly, and melted at high temperature to obtain a transparent Er-doped sodium silicate glass. There are abundant non-bridging oxygen in the high-sodium precursor, which can dissolve more rare earth elements, while the Er-doped sodium silicate glass has high silica content, strong chemical stability, and high practical value. The Er atoms in the raw material made by mixing glass-sooting and silica are physically uniformly distributed, which can reduce the Er atom clusters caused by the slow diffusion of ions in the high viscosity of the glass liquid during the melting process. Under the excitation of 980nm laser, Er-doped sodium silicate glass emits narrow bandwidth fluorescence at 1.5um, which has a good application prospect in L-band fiber amplifiers.
