| Abstract: | Absorption, transmission and reflection properties of hydrogen uranyl phosphate (HUP) are determined, by using pyroelectric (PE) sensors in thermally-coupled (PPE) and thermally-decoupled (conventional) spectroscopy configurations. Absorption bands at 1.25, 1.5 and 2.0μm, stronger for HUP than for the corresponding ammonium salt, have been observed. This can be correlated with the much higher protonic conductivity of HUP and suggests polaronic effects on the conduction mechanism in this solid electrolyte. |
