Room temperature red emitting carbodiimide compound Ca(CN2):Mn2+

Synthesis and Characterisation of the Nitridocuprate(I) Nitride Carbodiimide (Sr6N)[CuN2][CN2]2

“…For M = Hg two modifications, one cyanamide and one carbodiimide, are known , . Interestingly, some of these compounds show potential applications as negative electrode materials for lithium and sodium ion batteries, corrosion protective layers, photovoltaic devices, fluorescent light sources, and light‐emitting diodes , . Due to the carbodiimide anion being a pseudo‐chalcogenide anion, it can act as a bridging ligand to allow effective magnetic super exchange between bridged paramagnetic cations, as seen for Cr 2 [CN 2 ] 3 and M [CN 2 ] ( M = Mn – Cu), which are isostructural to their respective oxide variants, exhibit similar magnetic ordering and also have the same colours .…”

“…SrCN 2 , BaCN 2 and CaCN 2 can also be obtained from the reaction of their corresponding carbonates under an ammonia flow at high temperatures [3,5,15]. Additionally, solid-state metathesis reactions have also resulted in the formation of SrCN 2 from SrI 2 and ZnCN 2 between 570 and 700 • C for 24 h or CaCN 2 from and Li 2 (CN 2 ) at 500 • C for 48 h [6,16]. Finally, metallic flux route have also been applied to prepare SrCN 2 by a reaction of strontium iodide, cesium cyanide, and cesium azide at 800 • C for 24 h [4].…”

“…Over the past decade, concerted efforts have been in progress for the development of new materials with good performance what can lead to a significant decrease of the manufacturing cost. In this context, alkaline-earth carbodiimides materials received a lot of attention recently for their potential application as hosts for luminescent materials, especially for red phosphors [3,4,5,6]. Several [5,7,8].…”

Synthesis and photoluminescence properties of Mn2+ doped Ca1-xSrxCN2 phosphors prepared by a carbon nitride based route

“…As part of the family of nitrogenous materials, alkaline-earth (AE) carbodiimides compounds with the general formula AECN2 (AE = Mg, Ca, Sr and Ba) have received increasing attention due to their interesting luminescent properties [9][10][11][12]. The most famous member of the family is surely CaCN2 used as fertilizer since early 20 th century.…”
