Abstract: Abstract:The effect of laser illumination on the luminescent properties of MCM-41 was investigated by photoluminescence (PL) measurements. It was found that PL peak energy, PL intensity, and PL degradation of MCM-41 can be manipulated by controlling the laser illumination time. Laser illumination on MCM-41 gave at least a 2.5 times increase in PL intensity and an improvement in PL degrading phenomena. Possible mechanisms were proposed to explain our experimental results in a consistent way. The results presented here are expected to be useful for clarifying the nature of light emission from MCM-41 materials and to be of practical use for its possible applications in optical devices.
