Description
現在、精力的に研究が進められているのは、主にこの発光機構である。電子・正孔の再結合による発光は、半導体カーボンナノチューブ中に何らかの方法により電子と正孔を励起し、それらの再結合によって発光するものである。現在の固体半導体における発光ダイオード(LED)に対応する発光原理である。
あらゆる物質は、絶対零度を超える温度において熱による電磁波の放射(黒体放射)が見られる。この黒体放射では、その発光スペクトルはプランク則によって記述されるとともに、熱放射のエネルギーは温度Tの4乗に比例するステファン・ボルツマン則に従う。この黒体放射は、現在は例えば電球のタングステンフィラメントとして用いられていて、照明等に利用されている。
