In the present work luminescence properties of terbium trivalent (Tb3+) doped ZrO2 were studied. Ultrasonic spray pyrolysis (USP) technique was employed to deposit the films. PL emission of the ZrO2:Tb3+ films exhibits emission peaks around 489, 548, 588, and 620 nm corresponding to transitions 5D4→7F6, 5D4→7F5, 5D4 →7F4, and 5D4→7D3 was seen when excited by excitation wavelength 288 nm. TL glow curves for ZrO2:Tb3+ exhibit a glow curve with a well-defined peak centered in around 170°C. TL signal as a function of dopant concentration showed a maximum at 10 at%. The best intensity of TL response as a function of UV radiation wavelength was in 230 nm. TL response fading and reusability were also analyzed. The ZrO2:Tb3+ films has been found to have simple and sharp glow peak which should be considered for dosimetric applications.
