Polycrystalline samples of filled skutterudite phosphide La<sub>x</sub>Ce<sub>1-x</sub>Ru<sub>4</sub>P<sub>12</sub>(0 ≤ x ≤ 0.3) and La<sub>x</sub>Ce<sub>1-x</sub>Os<sub>4</sub>P<sub>12</sub>(0 ≤ x ≤ 0.5) were synthesized using high temperature and high-pressure techniques. The samples were characterized by x-ray diffractometry. The thermoelectric properties were measured. These properties include electrical resistivity, the Seebeck coefficient and thermal conductivity. La doping Ce based filled skutterudite phosphides enhanced the high power factor value of 0.7×10<sup>-3</sup>[W/K<sup>2</sup>m] due to a considerable decrease in the value of resistivity and thermal conductivity without much decrease in the Seebeck coefficient. It has been noticed that doping of more than one rare earth element caused a decrease in the thermal conductivity by increasing randomness and rattling effects.
