The preparation and characterization of thick InP layers by LPE with admixture of Ce, Tb, Dy and Yb is reported. Measaurement of temperature dependent Hall effect, C-V characteristics and photoluminescence spectra show the change of n-p type conductivity and considerable improvement of structural and electro-optical parameters for all studied rare-earth elements. Mn was identified as dominant acceptor impurity in the case of Tb and Dy addition. In the case of Ce and Yb the dominant acceptor was identified as isoelectronic Ce or Yb on the In site.
