Abstract

The photo-thermo-reflective (PTR) glass is fabricated by the high temperatur e and melting process. The sample is characterized by differential scanning calorimetry (DSC), Ultraviolet visible-near infrared spectroscopy, and X-ray diffraction (XRD). The experiment results show that NaF crystal is deposited in glass, the amount and the size of crystal phase precipitation can be achieved by controlling exposure dosage and time, thermal development temperature and time. At the same time, the reflective-index variation, about 5×10-4, was measured by interference measuring method method..
