Abstract
We have reported for the first time on visible photoluminescence (PL) in crystallized a-Si:H/aSiNx:H multilayers structure by CW Ar ion laser annealing treatments. In this paper we present new results on visible PL and electroluminescence (EL) from crystallized a:SiH and its based multilayers by using KrF excimer pulse laser irradiating treatments. Strong and stable PL and EL have been observed by naked eye in both laser irradiated a-Si:H and a-Si:H/aSiNx:H multilayers samples at room temperature. The EL peak of crystallized a-Si:H/a-SiNx:H multilayers is blue shifted from 1.79 eV to 2.00 eV with narrowing the well layer thickness from 4 nm to 2 nm which suggests the origin of the light emission should be related to the quantum size effect.
