Color tunability and white light generation through up-conversion energy transfer in Yb3+ sensitized Ho3+/Tm3+ doped tellurite glasses

Co-doping of Ho–Yb ion pairs modulating the up-conversion luminescence properties of fluoride phosphors under 1550 nm excitation

“…Then it will experience a radiative transition back to the ground state, producing green light emission, and this process is shown in Fig. 7(b). 28,29,31–34…”

“…7(b). 28,29,[31][32][33][34] The red-light emission of the sample at this time is similarly produced by the sum of the overlap of the characteristic emission of Er 3+ ions and Ho 3+ ions. For Er 3+ ions, the redlight emission is composed of two parts.…”

Instantaneous Color Tuning of Upconversion Emission in a Novel Lanthanide-Doped Monolithic Glass via Excitation Modulation

“…Partial Jablonski diagram of Ho 3+ , Tm 3+ , and Yb 3+ ions demonstrating radiative and nonradiative transitions along with energy transfer among different ions. Adapted with permission . 2019, Elsevier.…”

“…The compositions of Ho 3+ /Tm 3+ /Yb 3+ triply doped tellurite glasses investigated in this study are determined based on our previous work focusing on the effect of glass composition on the characteristics of PL spectra . A new set of samples containing a mutual sample (G2) with the previous work were synthesized in the current study to design a novel monolithic glass for obtaining color-tunable emission through excitation modulation (see Table S1).…”

Glass-based LED system for indoor horticulture: enhanced plant growth through Sm3+ and Tm3+ co-doped luminescent glasses

“…This finding underscores the significant role of lanthanide concentration in modulating the energy transfer dynamics and lifetime values of emissions in the studied glass system. 67 The energy transfer mechanism in the selected 0.25Sm 2 O 3 -0.25Tm 2 O 3 sample is elucidated in Fig. 5(c) using the Jablonski diagram.…”
