UV-vis absorption of NaTaO3

01 January 1970 1 7K Report

are there any one studying NaTaO3? Why NaTaO3 has two absorption peaks in UV-vis. my sample was fabricated at 1150ºC for 20h. many papers revealed such a profile. is it due to different phase structure of NaTaO3? please look at the attached picture.

I guess the attached article will answer your question:

Li, F.F., Liu, D.R., Gao, G.M., Xue, B. and Jiang, Y.S., 2015. Improved visible-light photocatalytic activity of NaTaO3 with perovskite-like structure via sulfur anion doping. Applied Catalysis B: Environmental, 166, pp.104-111.
