“…The molar volume ( V m ) of glass system remarkably decreases after incorporation of a little rare earth ions (<3%). The decrease of V m is attributed to decrease in bond length or inter atomic spacing among the atoms of glass network and it therefore results in compaction of glass structure .

A series of Dy3+/Eu3+ single‐ and co‐doped calcium borosilicate luminescent glasses were prepared by the conventional high temperature melt‐quenching method. A compact glass structure is obtained by the addition of Dy3+/Eu3+ ions, which is verified by the physical properties of synthetic glasses. As network modifiers, Dy3+/Eu3+ fill in the interspaces of glass network and contribute to the conversion of [BO3] to [BO4]. Dy3+/Eu3+ co‐doped calcium borosilicate glasses can emit white light, which consists of blue, yellow, and red light under 387 nm excitation. The emission spectra and decay curves of the white‐emitting glasses have proved the existence of energy transfer. The average lifetime of Dy3+ decreases from 0.251 to 0.165 ms with the increasing Eu3+ concentration. Changing rare earth ions concentration, CIE color coordinates of Dy3+/Eu3+ co‐doped glass shifts from cyan to white with increasing excitation wavelength. A white‐light emission is obtained when the concentration of Dy3+ and Eu3+ equals to 4% and 2%, respectively. Moreover, the Dy3+/Eu3+ co‐doped calcium borosilicate glass shows high‐thermal stability and it may be applicable for high‐quality white LEDs based on high power near ultraviolet (n‐UV) LED chip in the future.

“…As these RE ions with larger radius enter into the glass network structure, the spacing between atoms in the glass structure is shortened, which promotes the compaction of the glass structure. This can also be demonstrated by the decreasing tendency of molar volume ( V m ) and molar volume of oxygen (

V_{o}

), as listed in Table . OPD increases from 59.872 to 62.554 mol/L with the increasing concentration of Tm 3+ /Dy 3+ ions, indicating that more oxygen bridges are formed in the glass network structure and are beneficial to the compact structure of glass …”

A growing demand for white light‐emitting diodes (W‐LEDs) gives rise to continuous exploration of functional fluorescence glasses. In this paper, Tm3+/Dy3+ single‐ and co‐doped glasses with composition (in mol%) of 30P2O5–10B2O3–23SrO–37K2O were synthesized using the melt‐quenching method in air. The physical properties, glass structure, luminescence characteristics and energy transfer mechanism of the glasses were systematically studied. As glass network modifiers, Tm3+ and Dy3+ ions can densify the glass structure. Excitation wavelength and doping concentration of Tm3+/Dy3+ ions have a direct impact on the emission intensities of blue and orange light as well as the color coordinate of the as‐prepared glasses. A white light very close to standard white light can be obtained under 354 nm excitation when the content of Tm3+ and Dy3+ is 0.2 mol% and 1.0 mol%, respectively. The results of the emission spectra and decay curves reveal the existence of energy transfer from Tm3+ to Dy3+. The analytic results based on the Inokuti‐Hirayama model indicate that the electrical dipole‐dipole interaction may be the main mechanism of energy transfer. Moreover, Tm3+/Dy3+ co‐activated glass phosphor has good thermal stability and chrominance stability and it is a promising candidate for white LEDs and display device.
