“…The reduction in the emission intensity with Nd 2 O 3 content beyond 3wt% indicates the presence of nonradiative processes. This is attributed mainly to the cross relaxation process, the interaction between the excited Nd 3+ ions and consequent energy transfer between them, which reduces the population level 4 F 3/2 and consequently the intensities of the emissions …”

The Nd3+‐doped CaO‐Al2O–B2O3‐CaF2 glasses were prepared by melt‐quenching technique and their optical, spectroscopic, and thermo‐optical properties were studied. The density and refractive index showed an increase with addition of Nd2O3 at the expense of CaO. The electronic polarizability increases with Nd2O3 concentration due to the increase in NBO. The absorption spectra present characteristic bands of Nd3+ transitions from the ground state 4I9/2 to the various excited states. The luminescence spectra show Nd3+ emission at ~880 nm (4F3/2 → 4 I9/2) and ~1064 nm (4F3/2 → 4 I11/2), which increases with Nd2O3 up to 3 wt%. The experimental lifetime decreases when Nd2O3 content increases, mainly due to the nonradiative processes of direct energy transfer between Nd3+ ions (cross relaxation). Results of thermal coefficient of optical path length (dS/dT) for the CaBAl glasses did not present significant changes with Nd2O3 concentration. These with values are comparable to the Fused Silica, and lower than the values measured for the CAS and LSCAS glasses. The results point out this glass system as a good candidate to be used in the development of photonics devices.

“…The s m deviation in five different positions of the sample is within 3 ls, which means that the present glass is homogeneous and free of clustering. Fluorescence quantum efficiency (g) is another important parameter used to understand the lasing efficiency of host materials [6]. This parameter is commonly defined as the ratio between emitted light intensity and absorption pump intensity, and it is evaluated using [3]:…”

There are many reports on long persistent phosphors (LPPs) applied in bioimaging. However, there are few reports on LPPs applied in photothermal therapy (PTT), and an integrated system with multiple functions of diagnosis and therapy. In this work, we fabricate effective multifunctional phosphors Zn3 Ga2 SnO8 : Cr(3+) , Nd(3+) , Gd(3+) with NIR persistent phosphorescence, photothermal response and magnetism. Such featured materials can act as NIR optical biolabels and magnetic resonance imaging (MRI) contrast agents for tracking the early cancer cells, but also as photothermal therapeutic agent for killing the cancer cells. This new multifunctional biomaterial is expected to open a new possibility of setting up an advanced imaging-guided therapy system featuring a high resolution for bioimaging and low side effects for the photothermal ablation of tumors.
