By calculation of thermodynamics,analysis of crystal structure and study of TEM andeletron probe,it is first discovered that SiO2 can be acted as one of the he
This paper investigates the zero dispersion wavelength and dispersion slope control of hollow-core photonic bandgap fibres(PBGFs) by using a full-vector finite
The thermal shift of 5d energy level of Eu~(2+) doped in Sr_5(PO_4)_3Cl have been measured in 10~700 K.A simulation calculation was worked out with a modified t
