A series of Tb3+ doped cubic MgAl2O4 green phosphors were synthesized via hydrothermal method followed by a post-annealing process. The variation regularity phase structure, morphology, particle size and concentration quenching mechanism investigated. results showed that the crystal structure matrix materials was not affected when ions introduced. In addition, micrometer-sized rods excellent di...

Autonomous navigation of mobile robots is a challenging task that requires them to travel from their initial position destination without collision in an environment. Reinforcement Learning methods enable state action function suited During trial-and-error interaction with its surroundings, it helps robot find ideal behavior on own. The Deep Q Network (DQN) algorithm used TurtleBot 3 (TB3) achi...

In recent years, luminescent materials doped with Ln(3+) ions have attracted much attention for their application as optical thermometers based on both downshifting and upconversion processes. This study presents research done the development of highly sensitive in physiological temperature range poly(methyl methacrylate) (PMMA) films two series visible complexes (Ln(3+)=Tb3+, Eu3+, Sm3+) SiO2 ...

In this work, the effect of Ag⁺ on DNA sensitized Tb(3+) luminescence was studied initially using the Ag⁺-specific RNA-cleaving DNAzyme, Ag10c. While we expected to observe luminescence quenching by Ag⁺, a significant enhancement was produced. Based on this observation, simple DNA oligonucleotide homopolymers were used with systematically varied sequence and length. We discovered that both poly...
