Описание:
Nd1–xLaxGaO3 (0.7 ≤ х ≤1.0) solid solutions were synthesized by the ceramic method, their crystal structure, magnetic and luminescent properties were investigated. The solid solutions investigated behave as paramagnetics in temperature region of 5–300 K. Calculated values of Nd 3+ ion effective magnetic moment in solid solutions investigated are lower than theoretical. There probably exists „partial freezing” of orbital moment of Nd 3+ ions by the crystal field of the orthorhombically distorted perovskite structure of Nd1–xLaxGaO3 gallates. It is shown that Nd0.1La0.9GaO3 is an efficient phosphor with IR-emission, so it is prospective for use in IR-LEDs.
