Effect of composition and temperature on the second harmonic generation in silver phosphate glasses

Robust B-exciton emission at room temperature in few-layers of MoS2:Ag nanoheterojunctions embedded into a glass matrix

“…for the development of 0.3AgI-0.7AgPO 3 :MoS 2 architecture. In one of our previous studies it was demonstrated that the incorporation of AgI in the AgPO 3 glass results to the agglomeration of silver nanoparticles for the formation of larger silver phases 26 , while the phosphate network connectivity remains unaffected. Namely, it was reported that for the aforementioned nominal glass composition silver clusters (larger particles formed from the agglomeration of many nanoparticles) with an average size of 2.78 μm are formed while randomly positioned along the glass network (Fig.…”

“…5 b, c. Altogether, the appearance in discrete and enhanced excitonic emission is led by the exciton (MoS 2 ) and surface plasmon (glass) coupling in the nanoheterojunctions (Glass:MoS 2 ) system. Further work is currently in progress to optimize this coupling via tuning of the Ag NPs size and fraction 26 into the AgPO 3 matrix.…”

“…The selection of AgPO 3 glass as a host matrix is prompted by several reasons: First, its transparency in most of the visible range ( Fig. S1) enables the full exploitation of the AgPO 3 :MoS 2 photoluminescence properties towards various nanophotonic applications 26 . Moreover, the presence of silver nanoparticles (NPs) within the glass matrix gives rise to interesting optical phenomena that can be exploited towards enhancing and manipulating the PL properties of the incorporated MoS 2 layers.…”

Highly luminescent and ultrastable cesium lead bromide perovskite patterns generated in phosphate glass matrices

“…39,40 In this work, the selection of AgPO 3 glass is encouraged mainly due to its soft nature, low glass transition temperature (T g ) of 192°C, property of being transparent in most of the visible region, easy preparation, and non-toxic nature. 37,41,42 The composite perovskite-glasses developed here exhibit impressive photoluminescence (PL) stability over the tested period of two months, when compared to the corresponding PL of the air-exposed PNCs. More importantly, using a simple and fast cw-laser processing technique, we demonstrate the formation of permanent perovskite micropatterns.…”

“…In particular, all-inorganic lead halide PNCs are prepared following a previously described room temperature coprecipitation method, 6 while silver metaphosphate glass (AgPO 3 ) is employed as the hosting material. In recent years, phosphate-based glasses have been used frequently as the platform for many interesting photonic features such as second harmonic generation, 36,37 lasing, 38 and optical fiber applications. 39,40 In this work, the selection of AgPO 3 glass is encouraged mainly due to its soft nature, low glass transition temperature (T g ) of 192°C, property of being transparent in most of the visible region, easy preparation, and non-toxic nature.…”
