Regulating the photoluminescence and energy transfer process of Sr₅(PO₄)₃Cl:Eu²⁺, Mn²⁺ via pressure-induced phase transition

Abstract

Single-phase phosphor with emission covering the whole visible spectra is a suporior strategy for efficient white light generation, where color rendering index (CRI) / correlated color temperature (CCT) indices can...

Voltage‐Driven Molecular Orientation with Optical Synergy in Rare Earth Doped Polymer Dispersed Liquid Crystals

“…[11,12] Previous research has mainly focused on the traditional stimuli (e.g., ions, pH, temperature, or pressure), which may suffer from residual chemical effects or complex conditions for application. [13][14][15][16][17] Opto-electrically synergistic induced photoluminescence regulation could enable more flexible real-time reversible regulation of photoluminescence. However, limited by the design and synthesis process of materials, such regulation is still lacking.…”

Pressure-induced structural phase transition, irreversible amorphization and upconversion luminescence enhancement in Ln3+-codoped LiYF4 and LiLuF4

“…[24][25][26][27][28][29][30] In recent years, high pressure has been proved to be a robust tool in the optical fields such as pressure-induced emission (PIE), pressure-driven energy transfer and pressure-modulated application as luminescent pressure sensors. [31][32][33][34][35][36][37][38][39] Even the UC PL of Ln 3+ -doped phosphors, based on inner shell electron f-f transition, can also be altered by pressure, including the emission intensity, peak profile, lifetime, transition selectivity and quantum yield. [40][41][42][43] As reported, cubic NaYF 4 :Yb 3+ /Er 3+ nanoparticles presented a 1.7-fold UC PL enhancement at 2.1 GPa for the strain-induced modification of optical selection rules.…”
