“…At this point, blue-emitting Tm 3+ ions as a result of the 1 G 4 → 3 H 6 transitions are incorporated to glasses together with Dy 3+ ions to properly adjust the Y/B ratio and realize white light emission by increasing color purity. White light generation through Dy 3+ /Tm 3+ co-doped glasses have been investigated and reported in different glass matrices such as, alumino-borosilicate [102], oxyfluoride-germanate [103], tungsten-borate [104], zinc strontium phosphate [105], and lanthanum-phosphate [106].…”

Nowadays, solid-state white light-emitting diodes (wLEDs) have attracted remarkable attention for applications in general lighting, displays and numerous electronical devices due to their eminent efficiency, longer lifetime and higher mechanical durability compared to traditional incandescent and fluorescent lights. In current commercial wLEDs, a combination of Y 3 Al 5 O 12 :Ce 3+ yellow phosphor with blue LED chip and epoxy resin is generally used to generate white light. However, there are some considerable frailties mostly originated from phosphor and resin such as, degradation upon heat, and moisture, inhomogeneous spectral distribution, and poor color rendering capability. Therefore, phosphor embedded glass-ceramics have been developed as a promising way to obtain durable solid-state lighting devices. However, in these methods, there is a greater risk of reactions between the phosphor material and the glass host. At this point, lanthanide-doped luminescent glasses have drawn great attention as a new generation phosphor and/or epoxy free white-light-emitting source owing to their favorable properties including high thermal and chemical stability, high transparency, and easy manufacturing process. This review article aims to comprehensively summarize the recent progress in singly (i.e., Dy 3+ , Eu 2+ ), doubly (i.e.

Laser and optical properties (absorbance, excitation/emission and decay time data) of Dy 3? , Dy 3? /Sm 3? , Dy 3? /Sm 3? /Eu 3? -doped Li 2 O-Al 2 O 3 -ZnO-P 2 O 5 glasses are investigated. Laser spectroscopic parameters of the dysprosium yellow emission show potentialities of the luminescent glass as yellow laser medium under excitation at 348 nm. The Dy 3? /Sm 3? -activated glass tonality can be shifted from neutral white of 4559 K under 350 nm excitation to yellowish-orange of 2033 K (85.3% color purity) upon 372 nm excitation. A shortening of the dysprosium 4 F 9/2 level lifetime revealed that Sm 3? can be sensitized by Dy 3? by means of a non-radiative energy transfer that could be occurring into Dy 3? -Sm 3? clusters with an efficiency of 0.13. The Dy 3? /Sm 3? /Eu 3? -activated glass tonality can be shifted from warm white of 3387 K under 350 nm excitation to reddish-orange of 1638 K (92.1% color purity) upon 372 nm excitation. From lifetime data of the Dy 3? ion 4 F 9/2 and Sm 3? ion 4 G 5/2 levels is inferred that non-radiative energy transfers from dysprosium to europium and/ or samarium and from samarium to europium could be occurring into Dy 3? -Sm 3? -Eu 3? clusters with energy transfer efficiencies of 0.22 and 0.41, respectively.
