Abstract

The Ho³⁺-ions doped in CaO-SrO-BaO-B₂O₃ glass (BCBaSrHo) has been synthesis to study its emission, absorption, and decay time measurements. JO theory has been used to evaluate various radiative properties of BCBaSrHo. The increase in the density with Ho³⁺-ion concentration implies the tightly packed and compactness of the BCBaSrHo glass structure. The trend observed in JO-parameters are Ω₂> Ω₄> Ω₆. Higher value of Ω₂ indicates covalent nature of the bonding between Ho-ligands ions. The photoluminescence (PL) emission spectra of BCBaSrHo glasses have three emission transitions corresponding to transition. The (B_r = 0.63) for ⁵F₅ → ⁵I₈ transition thus BCBaSrHo glass. The⁵F₄(⁵S₄) → ⁵I₈ and ⁵F₅ → ⁵I₈ transition has highest value for σ. The CIE-color coordinates are x = 0.42, y = 0.55 for BCBaSrHo(0.5). All these results suggest BCBaSrHo(0.5) glass has potential high-gain and low-threshold application green and red laser.

激光应用中掺Ho3+的BCBaSrHo玻璃的绿、红发射研究

合成了掺杂在CaO-SrO-BaO-B2O3玻璃(BCBaSrHo)中的Ho3+离子，研究了其发射、吸收和衰减时间的测量。利用JO理论对BCBaSrHo的各种辐射特性进行了评价。密度随Ho3+离子浓度的增加而增加，表明BCBaSrHo玻璃结构的致密性。在jo参数中观察到的趋势为Ω2 >Ω4比;Ω6。Ω2值越高，表明ho -配体离子之间的键是共价键。BCBaSrHo玻璃的光致发光(PL)光谱有三个与跃迁相对应的发射跃迁。5F5→5I8的(Br = 0.63)转变为BCBaSrHo玻璃。5F4 (5S4)→5I8和5F5→5I8相变的σ值最大。BCBaSrHo(0.5)的cie颜色坐标为x = 0.42, y = 0.55。这些结果表明BCBaSrHo(0.5)玻璃具有潜在的高增益、低阈值应用于绿光和红光激光。
