文摘

Luminescent Eu-doped SiCxOy films were prepared at a low temperature of 250 °C. Thermal annealing causes the enhanced switchable red Eu3+ and blue Eu2+ PL. The intense light emissions can be observed with the naked eye in a bright room. The enhanced PL is due to the formation of high-density nanosized EuSiO3 cluster.
