Bulk Zn 1– x Be x Te crystals were grown in the range extending up to x = 0.12. Their structural, optical and photothermal properties were characterised using X‐ray diffraction, photoluminescence (PL) and photoacoustic (PA) methods. The lattice constants are found to follow a linear dependence on x . Energy gap and thermal diffusivity were determined from photoacoustic spectra. The energy‐gap increasing trend with rising beryllium content is in agreement with that reported for thin (Zn,Be)Te layers on InP substrate.
