摘要：

The supralinear dependence of visible photoluminescence intensity from amorphous silicon nanopowder produced in plasma enhanced chemical vapor deposition on excitation power and its exponential dependence on pressure is reported. It is shown that this new material emits two different kinds of photoluminescence that dominate at different pressures.
