Soda lime glass was implanted sequentially with Ti+and N+to doses ranging from 2 to 30×1016cm−2in order to study the resulting optical properties. Analysis of the implant distributions was made by using Rutherford backscattering and x‐ray photoelectron spectroscopy and revealed profiles which closely followed each other as designed by the selection of implant energies. Analysis of optical properties showed that the highest dose resulted in an increase in the fraction of infrared reflected by more than a factor of 4 versus 1.7 for the visible regime. The percentage of the total solar radiation rejected exceeded 60% at the highest dose, indicating that the buried layer is highly effective in reducing solar load. ©1995 American Institute of Physics.
