PENG YINGCAI, LIU MING, HE YULIANG, et al. EFFECT OF MEASURE TEMPERATURE ON PHOTOLUMINESCENCE PROPERTIES OF nc-Si:H FILMS. [J]. Chinese journal of luminescence, 1998, 19(1): 56-59.DOI:
nc-Si:H films were prepared using conventional PECVD technique
and its photoluminescence (PL) properties was measured under different temperatures.The results point out that PL peak energy have red shift of 54meV with temperature increase
but light intensity are expotentially reduced after T >80K.The shift of PL peak is due to shrinkage of band gap
and reduction of PL intensity is due to that non-radiation combinations play an important actions in the light emission properties of nc-Si:H films.
