Europium (Eu) doped Calcium borophosphate (CBP) phosphors were synthesized via the solid-state diffusion method. The prepared Europium (Eu) doped Calcium borophosphate (CBP) powder was heated up to 600 ℃ for 6 h for a complete diffusion of ions in the powder system. XRD results showed that the prepared phosphors exhibit a well-crystallized hexagonal phase. The complete diffusion inside the CBP/Eu powder system has been confirmed by the presence of elements such as P, O, Bi, Ca, C, Eu, and B. Apart from that, the synthesized powder system has shown a down-conversion property where the Eu³⁺-activated ion was excited at 251 nm. Under the excitation of 251 nm, CBP/Eu phosphor showed intense emissions peaking at 591,617, and 693 nm due to the ⁵D₀ → ⁷F₁, ⁵D₀ → ⁷F₂, and ⁵D₀ → ⁷F₄ transition of Eu³⁺ ions. The obtained results suggest that the CBP/Eu phosphors have the potential for spectral response coating materials to improve photovoltaic (PV) panel efficiency.

In the current context of information technology development, many vocational colleges are reforming and developing their education majors in the direction of information technology. Now that we have entered the era of informatization, the direction of reform and innovation in the education industry can be considered to use the development methods of informatization to improve the comprehensive efficiency of teaching. In the context of informatization, the teaching of pharmacy majors in vocational colleges needs to seize the development advantages of informatization, reform classroom teaching methods, and improve teaching efficiency. This article mainly discusses how to integrate the teaching reform of pharmaceutical majors in vocational colleges with the development trend of informatization, achieve better reform and development efficiency, and cultivate pharmaceutical professionals.

With the accelerated pace of society and increasingly fierce competition across various fields, people’s daily stress continues to increase, and anxiety disorders have gradually become a prominent issue in the field of public mental health. Using the psychology work When Panic Attacks: The New, Drug-Free Anxiety Therapy That Can Change Your Life as an example, this paper explores the application of Relevance Theory in the translation of psychotherapy popular science texts. It summarizes the textual features and translation principles of psychotherapy popular science texts, and analyzes the methods and strategies to achieve optimal relevance between the source text and target text on the lexical and syntactic levels, aiming to provide references for future popular science translation practices.

Lei's work explores the theme of existentialism, reflecting the anxiety and uncertainty that modern people experience in the face of a rapidly changing world. The stories explore the dislocation and suffering experienced by modern people in a heterogeneous cultural space, the anxiety of existential existence, and the alienation and dislocation of interpersonal relationships.

Taking domestic single-player game brands as the research object, this paper discusses the value and strategy of single-player game brands expanding IP operation. It is found that single-player game brands expanding IP operation can improve brand awareness and influence, increase player stickiness and loyalty, and extend product life cycle and market vitality. In order to help single-player game brands expand IP operations, this paper puts forward four suggestions, such as creating core stories, hoping to provide some reference and inspiration for the development of domestic single-player game brands.
