Lead diiodide has been proposed as a solvent for liquid‐phase growth of PbTe layers on BaF 2 substrates. The contact with pre‐eutectic (PbI 2 ‐PbTe) solutions has resulted in deposition of PbI 2 islands of spherical cupola shape. The relatively small contact angle (16–25) indicates heterogeneous nucleation. At certain experimental conditions dense layers of PbI 2 have also been prepared. This crystallization is an indirect evidence for good wettability of the BaF 2 substrate.
