  for the trans−cis isomerization of N2F2 has a barrier of 60 kcal/mol and involves rotation about the N═N double bond. This barrier is substantially higher than the energy required for the dissociation of N2F2 to N2 and 2 F. Therefore, some of the N2F2 dissociates before undergoing an uncatalyzed isomerization, with some of the dissociation products probably catalyzing the isomerization. Furthermore, it

  A novel red fluoride phosphor NKSF:Mn was obtained at room temperature by controlling the ratio of NaF to KF. The chromaticity coordinates of phosphor NKSF:Mn are very close to the CIE coordinates of ideal red ascribed to the contribution of particularly strong zero-phonon lines.

  在室温下通过控制NaF和KF的比例获得了一种新型的红色氟化物荧光体NKSF:Mn。NKSF:Mn荧光体的色度坐标非常接近于理想红色的CIE坐标，这归因于特别强的零声子线的贡献。
