Exploring different types of materials in triboelectric nanogenerator (TENG) research remains a dynamic and evolving field. This work marks an important milestone in this journey by introducing phosphor material, particularly zinc vanadate (Zn 3 V 2 O 8 , ZVO), into TENG technology for the first time. TENG uses ZVO and silicone films as active triboelectric layers. The fabricated TENG exhibits remarkable performance, producing an output voltage of 515 V and a current of 178 μA, resulting in an impressive power density of 6.9 W/m 2 . Furthermore, we demonstrate the practicality of this innovation by powering 360 series-connected LEDs and electroluminescent devices with a simple hand tap. In addition, the luminescence properties of ZVO are also investigated. This research work opens up possibilities for multifunctional applications, harnessing the potential of phosphor materials for energy harvesting and beyond.

“…The high-power Tm laser also resulted in significant thermal loading, which affected the overall stability of the longwave laser system. Diode -pumped Ho lasers exhibit notable characteristics of high efficiency, high power and simple structure [10][11][12][13][14][15][16], which are promising pump source for compact long-wave ZGP OPO systems. In this paper, we demonstrated a high power long-wave infrared ZGP OPO system at 9.8 μm based on type-I phase matching ZGP crystal pumped by a diode-pumped AO Q-switched Ho:YAG laser.…”

We describe an efficient long-wave infrared optical parametric oscillator based on ZnGeP2 crystal pumped by a diode-pumped AO Q-switched Ho:YAG laser in this paper. The wavelength of the laser pulse generated by Ho:YAG laser is 2.09-μm, and the maximum output average power is 25.3 W at repetition rate of 10 kHz. When pumped by such Ho:YAG laser, the maximum average output power of 0.66 W at 9.8 μm is achieved, corresponding to slope efficiency of 5.0% and optical efficiency of 2.6%. Furthermore, the beam quality factor of the long-wave infrared beam is measured to be approximately 1.3. To the authors’ best knowledge, this is the best performance reported for a long-wave infrared ZGP-OPO pumped by a diode-pumped AO Q-switched Ho:YAG laser.

“…2 μm solid-state lasers utilize Tm 3+ /Ho 3+ -doped matrix materials as the laser gain medium, harnessing energy transitions from these rare earth elements to directly produce 2 μm laser output [7][8][9][10][11]. The choice of matrix material significantly influences the thermal and mechanical properties of the laser gain medium.…”

We present a high-efficiency continuous-wave Ho: LSO laser wing-pumped by a 1.91 μm laser diode. The impact of different output transmittances on the laser output power is compared and analyzed. The optimal result was achieved with a −500-mm radius curvature and a 6% transmission output coupler. The maximum output power of the Ho: LSO laser is 7.81 W, with a slope efficiency of 44.7%, a center wavelength of 2,106.6 nm, and beam quality factors of 1.4 in the x-direction and 1.3 in the y-direction.
