（氧）氮化物材料具有与氮所起的作用直接相关的吸引人的性质。常用的合成方法包括氧化物前体在流动的氨中的热氮化。作为一个结果的阴离子N3-/O2-取代的结果增加的共价字符，说明了向更高的波长值的吸收边的移位。因此，氮氧化物在着色颜料、紫外线吸收剂和可见光光催化剂领域中提供作为光学材料的潜力。
(Oxy)nitride materials have attractive properties directly related to the role played by nitrogen. A commonly used synthesis method consists of the thermal nitridation of an oxide precursor in flowing ammonia. As a consequence of the anionic N3-/O2- substitution results an increase in the covalent character, illustrated by a shift of the absorption edge towards higher wavelength values. Thus, oxynitrides offer potentialities as optical materials in the domain of colored pigments, UV absorbers and visible-light photocatalysts.
