Abstract:
terbium-europium co-doped sodium aluminum silicate (NaAlSiO_4:Tb ~(3 +), eu ~(3 +) luminescent materials. The synthesized samples were characterized by powder X-ray diffraction (XRD), fluorescence spectrum (PL), time-resolved spectrum (TRPL) and fluorescence lifetime. The results show that by changing the doping concentration of Eu ~(3 +) in NaAlSiO_4:Tb ~(3 +),Eu ~(3 +), the green and red emission can be controlled. Due to the effective energy transfer between Tb ~(3 +) and Eu ~(3 +) ions, Tb ~(3 +) co-doping of ions can significantly enhance the luminescence properties of Eu ~(3 +) ions in the Matrix. The energy transfer phenomenon can be confirmed by TRPL spectroscopy and other means, according to the numerical calculation of fluorescence lifetime, the energy transfer efficiency from Tb3 ~(3 +) to Eu ~(3 +) ion is up to 95%.

Abstract:
A method for producing chrome-free white wet leather tanned with aluminum Sodium silicate is introduced in this paper. The white wet leather is colorless, clean, easy to store, well formed, and convenient for mechanical processing in the subsequent process. The generated cut layer and cut the waste can be made into agricultural long-acting nitrogen fertilizer. From the white wet leather can be processed to a stable quality of many types of finished leather. The tanning effect of aluminum sodium silicate, the chemical knowledge of artificial zeolite and protein, the distribution of tanning agent in leather, the interaction between tanning agent and other tanning aids, the application of waste materials in agriculture and the comparison of sodium aluminum silicate with other tanning systems are reported in detail.
