Single-phase crystalline films of PrSb2 were prepared by vacuum thermal evaporation from two independence sources on various substrate. That is shown the temperature of Sb evaporator influence on colour and accordingly on valence of Pr ion of PrSb2 thin films. The films have golden, black and blue dark colour. Absorption spectra of golden colour of PrSb2 thin films were measured at 300 K and photon energy was 0.05-5.5 eV.
