This contradiction arose from the very beginning of extended study. In this report we studied the blue spectral shift in the newly discovered solid state cathodoluminescence when the applied voltage is increased. There are three different kinds of spectra in three intervals of applied voltage. The reason of this spectral shift is found to be the field ionization of exciton. The switching on of recombination starts only after the beginning of this field ionization. The exciton emission obeys molecular theory and the recombination obeys band model. Thus the demarcation is the appearance of field ionization of excitons. Since the ionization changes with electric field continuously, there is a region of coexistence of these two processes.<\/jats:p>","DOI":"10.1063\/1.1861134","type":"journal-article","created":{"date-parts":[[2005,2,3]],"date-time":"2005-02-03T23:04:46Z","timestamp":1107471886000},"update-policy":"https:\/\/doi.org\/10.1063\/aip-crossmark-policy-page","source":"Crossref","is-referenced-by-count":13,"title":["Why is the band model not contradictory to molecular theory in organic electroluminescence?"],"prefix":"10.1063","volume":"86","author":[{"given":"Zheng","family":"Xu","sequence":"first","affiliation":[{"name":"Institute of Optoelectronics Technology, Beijing Jiaotong University , Beijing 100044, People\u2019s Republic of China and , 4200-072 Porto, Portugal"},{"name":"Departamento de Fisica, Instituto Superior de Engenharia do Porto , Beijing 100044, People\u2019s Republic of China and , 4200-072 Porto, Portugal"}]},{"given":"Chong","family":"Qu","sequence":"additional","affiliation":[{"name":"Institute of Optoelectronics Technology, Beijing Jiaotong University , Beijing 100044, People\u2019s Republic of China"}]},{"given":"Feng","family":"Teng","sequence":"additional","affiliation":[{"name":"Institute of Optoelectronics Technology, Beijing Jiaotong University , Beijing 100044, People\u2019s Republic of China"}]},{"given":"Fujun","family":"Zhang","sequence":"additional","affiliation":[{"name":"Institute of Optoelectronics Technology, Beijing Jiaotong University , Beijing 100044, People\u2019s Republic of China"}]},{"given":"Lijian","family":"Meng","sequence":"additional","affiliation":[{"name":"Departamento de Fisica, Instituto Superior de Engenharia do Porto , 4200-072 Porto, Portugal"}]},{"given":"Xurong","family":"Xu","sequence":"additional","affiliation":[{"name":"Institute of Optoelectronics Technology, Beijing Jiaotong University , Beijing 100044, People\u2019s Republic of China"}]}],"member":"317","published-online":{"date-parts":[[2005,2,4]]},"reference":[{"volume-title":"Primary Photoexcitations in Conjugated Polymers: Molecular Exciton Versus Semiconductor Band Model","year":"1997","key":"2023062116083989900_c1"},{"key":"2023062116083989900_c2","doi-asserted-by":"crossref","first-page":"803","DOI":"10.1016\/0038-1098(89)90913-7","volume":"72","year":"1989","journal-title":"Solid State Commun."},{"key":"2023062116083989900_c3","first-page":"404","volume":"137","year":"1989","journal-title":"J.
