The origin of visible luminescencefrom “porous silicon”: A new interpretation

Luminescence and vibrational properties (infrared and Raman) of anodically oxidized (“porous”) silicon and of chemically synthesized siloxene (Si 6O 3H 6) and its derivates are compared. Based on the quantitative agreement of these two types of materials it is concluded that the origin of the strong...

Description
Summary:Luminescence and vibrational properties (infrared and Raman) of anodically oxidized (“porous”) silicon and of chemically synthesized siloxene (Si 6O 3H 6) and its derivates are compared. Based on the quantitative agreement of these two types of materials it is concluded that the origin of the strong room temperature luminescence in “porous” silicon can be traced to siloxene derivates present in “porous” silicon.
